Hi, thank you very much for your comment. I started teaching quite late in my life, around 42 years old. I chose the level of end of high school / early university because I remember as a student, that was the hardest period in my student life. I was lost in physics and maths, although I felt in my guts that was the path I wanted/needed to take. Luckily I managed to get my baccalaureat with 50,04% haha, and then was blessed with fantastic and passionate teachers in my early university that helped me bloom up to the PhD... Of course, the first step in becoming a teacher was to study the current high school programs, under the angle provided by wisdom and serenity that comes with higher age. And, I had so many "haha moments" ! As an engineer , try it, you'll be surprise how much progress you'll make in your own field. High school content in Physics (and maths) is sooooo crucial, and when well understood, very powerful: the way it is approached by the teacher can shape the life and the success (or not) of the student. I remember the horrid and incompetent teachers I had in high school, that nearly destroyed me, and the amazing ones I had in Uni, that really cared... And from that defined my own approach. It all comes to the basics... Once a student understand the physics behind an equation, and can handle at least a little algebra, he or she can truly excel, and bloom. Once on the right intellectual path, there is no place that the student cannot explore by himself. That's why I made teaching my life...
@@PhysicsMadeEasy Thank you very much for your kind response. I enjoy maths and physics more now than I did when I was my son's age. The difference, apart from a mature outlook is, no pressure to pass exams. In my time, there was no internet but great textbooks which I still have. However, I did find the leap between A' Levels and university a very big one, and I really struggled in the first year of my Aeronautical enginnering degree. The amount of practicals, and subjects covered was overwhelming for me. After I graduated I decided to go straight to industry and I have had a great career in the aerospace, and marine industries. I would agree that teaching/tutoring is great fun but requires a lot of preparation and thought in how to communicate the information. It is not easy being a teacher in my opinion, and it is criminal that here in the UK teachers are not given the respect they deserve. Fortunately, I have the benefit of videos such as yours which I use as part of my preparation, and also for my enjoyment. I wish you health, happiness and all the best in your endeavours. Thank you for the knowledge.
You're awesome dude, I'm a medical student learning about electromyographs and this helped me understand a concept in physics which is a subject I'm not good at.
Hi Anas, I noticed with a vast majority oif my students that they didn't understand what an electric potential is... They get by, by following the rules, but as soon as they are faced with a slightly different problem, they are lost, hence this video! I am glad it helped you with your studies :-)
I've been watching RUclips videos about physics since the beginning of high school and now I'm shocked that I have never came across to your channel before! Your explanation was incredibly helpful. Thanks a million. You kinda saved my life sir. P.s. I subscribed.
Hi Aysooda, thank you for your kind words. I am glad that the videos of my channel help you in your studies. Thx for subscribing. I hope you will enjoy the future content too :-)
Most school textbooks tend to define electric potential the 'tougher' way around. "Potential is the work done.. blah.. blah." Is it necessary to complicate things this much? Why can't they write it the 'natural' way? Kudos to them for complicating a simple notion into an abstruse monster. And Many many thanks to the you, professor! This was a masterpiece!
Hello sir ..i am from India .. studying in 10th grade ... I was not able to understand this concept.. .. but this video helped me ... Thank you so much
You are welcome Atul, I am glad my work helped you. In Grade 9-10, that is when a student starts to be confronted with this concept. If you continue in science, you will see the notion of potential showing up all the time, so it is essential that you understand it well as soon as possible!
When i listen to him, i'm so moved by his humble way of teaching, where he can explain such complicated things in such a simpler way. such teachers are gems. cause all my life i only had teachers who used very complicated and hard words to explain things, it definitely is the reason why most of people feel so stressed with the subject. thank you sir, for changing my view of understanding physics.
Thank you Mahami for this heartwarming comment! Indeed, I agree, when a student understands his/her stress level decreases thus his/her health and quality of life improves. This is why it is really important for teachers to structure the ideas and make them easy to understand. We are a kind of doctor!
My view of voltage has forever changed, thank you so much for your explanation! I would not understand every detail on the first go but the picture you've left in my mind is priceless!
Our whole nervous system and brain works because of local potential differences, that causes charged particles (ions and molecules) to move around and do what they are supposed to do. For example, me scripting and shooting this video, was a firework of electrical sparkles in my brain. I am glad that you experienced also such firework when viewing the video ;-) .
@@PhysicsMadeEasy I have a quick question. Let’s take a circuit, that has a resister. Let’s also say the voltage of a battery is 9V. Now all the voltage drop is across the resistor. Yet, the circuit keeps moving after the voltage drop.I don’t understand how exactly that is possible. If you have a battery of 9V and and voltage drop across a resistor of 9V, why does electrons keep moving. Would it have already lost all the potential?. A second question as well. When electrons go through a resistor, it loses kinetic energy by collisions with other atoms. Then how can the Amperage entering the resistor equal the amperage out of the resistor?.
@@MarkSmith-vo1vn Hi Mark, your confusion comes from the fact that you consider that the energy provided from the battery is transferred to the Kinetic Energy of the electrons… The energy provided goes to the Potential energy of the charges they carry. Through the resistor, it is the charges that lose energy. Just to give you a perspective. Mass of an electron: around 10^-30Kg, typical drift speed of an electron: around 10^-5 m/s. KE = 0.5mv^2, that’s around 10^-40J. Potential energy (= qV) of the charge carried by an electron, placed at a potential of 9V that’s around 10^-18J. That’s 10 billion trillion times larger. If you want, you can see the electrons continuing to move because they are just pushing each other like dominos… They are kind of “drifting”, hence the term ‘drift speed’. Ina circuit, the energy transfers relates to the PE of the charges.
@@PhysicsMadeEasy So all the kinetic energy gets turned into thermal energy. And The electron repulsion gives the potential Therefore the electrons have the same speed. So, then my next question is why doesn't electric potential decrease as you get closer to the protons. Is it because it is all relative to the electrons pushing it. I am kind of confused whether the potential of repulsion or the potential to go to the protons. Or does it balance out. The closer you get to the cathode the further you get from the anode.
Such an illustrative and simple way to explain something that seems so complex. Even a physics inept like me was enlightened, thank you sir keep up the great content
sir i got confused on this topic since 2 moths and i tried to understand the concept but i can't understand , finally today you have clear my all dought , thanks a lot
Hi Shambhu, I love reading these kind of comments because these reflect the exact objective I set for making these videos. Thanks for letting me know! It makes my day :-)
I’m an undergrad taking electrodynamics, and after this video I FINALLY have a grasp about the potential! I honestly had a better grasp on electric potential than gravitational potential, which always confused me when it came up in classical mechanics, such as the explanation for Lagrange points.
Amazing video finally got a hold of what potential really was after studying the entire electrostatics!This video really helped clear those concepts.Just had a small doubt..why do we define potential as the work done in moving a unit positive charge from infinity to that point?
Hello Mayamo... the definition of the electric potential is kind of a the starting point... It is the energy per unit charge that an object has when placed at a given position. It is therefore equal to the work that has to be done on that object to place it there...
@@PhysicsMadeEasy But according to the definition, you would have to bring the object there all the way from infinity, right? And that is equivalent to the area under the graph that you drew (assuming there are no other electric fields on the way to the destination). I am just trying to wrap my head around this infinity thing...
Thank you Aman, You know, I do not need to be overrated haha! As long as I unlock understanding blocks in many students around the world, I attain my goal.
Awesome you are the best communicator I have met and I am a professional civil engineer, but had difficulty understanding voltage. Thank you very much.
Hi there, thank you for your feedback. I am glad I could clarify this for you. By following rules, you can always manage without really understanding the physical concept behind voltage (tbh, I went through a large fraction of my uni studies that way). Maybe you can go back into passed projects where this concept was used, and see what you could have done better. I certainly did when I finally got it!
Lucid, direct and clear explanations. Something to note about a common point of confusion is the difference in nomenclature between the concept of energy and work. This really helped to make that difference stridently clear and really helped to tie it all together Thank you Dr. Reny🙏
Hi Paradox. You are welcome, and thank you for the encouragement! I am glad it helped you unlock the understanding of such an important concept in physics!
I'm in uni and I've been dealing with these notions for years and it feels like I've never really understood them until now. Thank you so much what a great teacher!
Thank you Marie for your very kind words. If my video brought you a new understanding, then dig out your old school and Uni notes related to electrical sciences, especially those you are still fuzzy about, and rework them with that new understanding...Haha moments await you :-)!
Dear Dr. Reny, I really appreciate the quality of and effort behind this video ranging from the animations and intuitive explanations to even the changes in location while explaining said concept, as a student this really helped me grasp a vital concept i was unable to before. I thank you very much for making this video.
Hello Tango. Thanks you so much for your wonderful comment. I am glad my approach helped you understand and assimilate such an important concept. Review your previous class notes (those you took before you understood what an electric potential was), and reconstruct them based on your new understanding. Be ready to get crowded with 'ahah' moments :-)
I wonder too... My channel is kind of a reaction to the hard time I had in High School. Still they exist: some lucky students are exposed to such teachers (I had some at Uni that took the time to make me bloom, and they became my inspiration)
You're really really great sir! I'm undergraduate degree physics student and I was struggling to understand the concept "potential" in physics.You just made it clear for me. I want to be great teacher like you who can make things clear for others.Thank you sir🙏
Hello Adane. Wow, I am so proud if I can inspire you in taking a teacher's career. It's one of the most wonderful jobs in the world. Actually, I was inspired during my undergraduate years by a teacher in electrochemistry (A topic at the time I hadn't understand). He was a little rough with us students but he was precise and clear. And when things are clear, the subject can now become interesting! That made me want to be like him (even if I am a little more patient with my students than he was, haha)! With you wanting to become a teacher too, maybe the circle is complete :-)!
@@PhysicsMadeEasy in the same way as your electrochemistry teacher inspired you, I'm really inspired by you and I'm sure you are and will be an inspiration for many. I love the way you explain things and thanks sir for give your time to reply and for your every lecture videos 🙏
I'm 27 and some how managed degree and job without understanding much physics but a part of me always want to understand how everything happening around me, thank you sir.
Amazing! I‘ve tried to understand the voltage so many times through other videos, but you are the best I fully understand the voltage. Thank you so much.
Amazing explanation and even more amazing visuals. Superb content. Please continue doing more physics videos! It is a massive help to students like me who self study!
Hello Malek, Thank you very much for your kind (and motivating) words. I will try to find some time for that. And I am super glad my work does help so many students around the world. Good luck with your studies!
It Is unbelievable to see a professor like you I wasn't able to understand this as in India as many comments say don't have that good professors/teachers But Today I finally Understood the Concept Each Bit :D Another surprising thing is you are actually clearing doubts of Each guy in comment section as well ! Subbed and Liked The Video Sir
Hi sir, I am currently doing my Master in Electrochemistry and after watching this video I realized that until today I did not know what actually electric potential was. I am eternally grateful to you, keep going!
Hi Medina, thank you for your comment. I studied some electrochemistry at Uni, a hard topic but one I enjoyed because of it being so borderline between Chemistry and Physics. Then, when I worked as a researcher for a large company, I used my free research time to create an electrochemical lab because I was interested in looking at the impact of chemically induced films (oxides or organic) for the corrosion inhibition on various metals (in pipes for example). I was quite successful at it. The strange thing is that me too, I did not have a good understanding of what an electric potential exactly is. I had made my own idea, close enough for what I was doing, but when I reviewed the school physics programs before starting my teaching career, I realised I hadn’t really understood it. I wish I had, because it would have made me much more powerful in my research: I probably would have won a Nobel prize lol! I also realised that not many people do understand electric potentials. A friend of mine is an experienced electrician, working in that field for years. He worked the electricity of my house ( I paid him for that), One day, I asked him, what does 9 volts means… He only knew the water analogy, but not the real meaning… So your comment did strike a sensitive chord: I am so glad I made you more powerful than I was. This makes me shiver as a teacher:-) ! Good luck and I wish you much enjoyment with the study of this great subject!
Sir I opted out of by graduate of electronics and communication engineering course because I was not convinced of what I was taught This is the first time in last 31 years,that I have understood the concept of electricity from your tutorial. Hats off to you God 🙌 you!!
Hi K.G. this is one of the most heartwarming comments ever, Thanks! It's a shame you didn't hold on to your graduation course. Often, specially at the beginning, it is necessary to just accept what is taught. Then, with time, the brain connects the dots, and things get clearer. Still, you chose another direction, and you may be fulfilled with it today, so no regrets! You can always continue studying physics as a hobby!
@PhysicsMadeEasy Thanks I choose financial management & Work as an analyst. Nevertheless, I keep updated on technical learning. Your videos unlock the cause & effect, Which is how physics should be taught.
Omg, this concept gave me a headache when I tried to listen to the lecture of my professor. On another you explained this in an extremely easy way to understand. Thank you so much sir !!!!!
Hi Sang, I am glad my work helped you unlock this crucial concept for you. Electric Potential It is not a concept that is difficult to grasp, but it can be a pain for students if not explained properly. And this is why I created this channel! Good luck with your studies of Physics!
Excellent explanations of electric potential and electric potential energy. The concept is simple but for some reason I get them confused. Now the fog has cleared and it makes my understanding of electronics easier.
Thank you for telling me this! This kind of comment is one of the reason why I have created this channel: To help girls and guys like you lift the mist that hinders the understanding of some basic concepts in a topic that you are passionate about. Enjoy the clearer skies!
Thank you! When I started teaching, I realised students had no clue about what is an electrical potential. They were just getting buy by applying the rules. I actually asked an electrician, friend of mine, that I employed to do some of the electricity in my house, he actually didn't know exactly what it was, just how to handle it in his job. I said to myself, I need to do something about that!!! Hence this video. I am glad it was so helpful to you :-)
Thank you! It's probably because I do not like having ads on my videos, thus, they are not promoted by youtube (Although I heard RUclips is going to force it soon)! Don't hesitate to share the channel link or the videos, so that others can enjoy some Physics fun!
Yes, understanding electric potentials is crucial when dealing with all electrical sciences. That's why I made this video. I am glad you appreciated it :-).
This helped a lot. I've been searching for a good explanation of electric potential for a lot of time. I couldn't wrap my head around the idea that a bunch of charges of a battery have a potential. But this video explained that it's more about potential energy that these changes are "making" with their field's. And thank you!
Yes, charges do not have a potential. They are positionned at a location with potential, but themselves do not have potential. Because they are positionned at a location with potential, they get potential energy (work was needed to bring them there). I am glad it clarifies things. Still, can you rephrase your last sentences so I can check that you really got it?
Hi Simbaland, you are warmly welcome. It makes me happy to have helped you understand such a fundamental notion. Now enjoy all the other understandings you can explore from the concept of electric potential. :-)
Thank you for this video, it really made me better understand electric potential (EP). There is one thing I don't get - according to the EP definition, you would have to measure the energy spent to bring the positive charge all the way from infinity to the point of destination. Wouldn't that be equal to the area under the graph you drew? Also, how about other electric fields that the positive charge might encounter along the way? This infinity definition is kind of hard to wrap my head around.
Hi Narnia, The idea of infinite distance from the charge source of the electric field is a conceptual idea… If infinities bother you, you can change the definition to: an electric potential at a position is the work required to bring a charge to that position from a point where that charge is not under the influence of any electrical interaction. No the PE would not be the area under the graph… Because V=kQ/x, the area under the graph would be a quantity proportional to the charge creating the field. When you have these kind of questions you can also check units! The area of a electric potential-position graph has a unit is J/C multiplied by meters, so not that of an energy.
@PhysicsMadeEasy Thank you so much for your comprehensive and kind response! It helps me understand better. We can basically choose the reference point anywhere, and define that the EP there is 0. And yup, I see now that my statement about the area makes no sense :)
@@narniabusiness7810 Yes. The reason why we place the charge at infinity is because of Coulomb's law (inverse square law with distance). In reality, whatever the distance between two charges, there will always be an interaction, even if extremely small. That is why we need infinity to make that interaction zero within the context of an absolute definition (a definition, by definition (punt intended;-) ), cannot contain approximations).
Great video and explanation! It was absurd for me what Electric "Potential" is, when I was introduced to it You made it so simple :) Thank you very much
Thank you Mareena, I am glad you find my videos useful: It's the whole goal of my channel to help students that are struggling with these concepts. I choose the topics just by observing my own students... Please feel free to share with anyone that can benefit from these!
thank you sir!!!🙏 before this video I'm confused about electric potential and voltage but after this videos it become very easy to understanding this for me
Hello Roy, that's fantastic: it is for this kind of result that I made this channel (I was in a similar situation as a student). Now, go back to your class notes about electricity, and read them again with this new understanding. Like pieces of puzzle, they should start to make much more sense :-).
Hey John, thanks for noticing :-). Indeed, it gives a little air, to have these little interludes outside where what was seen is briefly summarized: It makes it more pleasant to watch, and in the end, might stick better in the viewers head. I should do this on more videos!
Thankyou so much. You're indeed a saviour for me, i had been struggling with solving those questions I had while studying the concepts from weeks. While some are left, this was very beneficial for me. Thankyou.
Hi Angu, thank you for letting me know. I am really glad I unlocked some concepts for you. So yes, good idea to jump back to your old notes and exercises, and see how these make sense now!
Really need you as my physics tutor for iit jee indian examination one of the world toughest examination. Please upload more such videos. I watched many professor videos like walter lewin, prof carlson, and many more others. List is huge i could never understood this term properly. But watching this 8 minutes video i felt like how easy physics is you just need a good tutor
Thank you for your very kind words. I am glad that my work helped you out. With all my students, I very much insist on a good understanding of the basics: Bright students can manage without sometimes, by just using the rules, and mimicking standard exercises, but sooner or later they become limited in their ability to understand more advanced concepts and can lose interest in the topic, although they would have become amazing physicists otherwise...
I have been scouring youtube as I try to catch up in my physics class. You have got to have some of the best explanations I have seen. I loved your analogy to gravitational potential energy as it really cleared everything up for me. I cannot tell you how sick I am of the goddamn water pressure analogies lol! Thank You!
Hi Diego, the water analogy... me too! I do use it for the lowed grade students that do not understand yet how to manipulate the concepts related to energy, but I do tell them that they will have to fade it out once they get a better understanding. Thank you for your encouragements!
Hello Steve, That's the spirit! Explaining these concepts in 10 minutes can make the video quite intense... I am really glad you are making the most of them by viewing them multiple times. And if you have questions, there is the comment section :-)
Thanks Aryan, as long as I help students around the world, I am fine without the million views :-)! Being a RUclips Star would put too much time pressure on me haha, I have my real life students to take care of!
@@PhysicsMadeEasy It was really helpful and that night was a tough night for me. So when I watched the video, I wanted to comment something good, but I wanted to say it in the way I would fell the most, that's why I wrote it in my first language. Thx for translating it!
Subscribed sir, I'm seeing this is what the students needed to understand about all of this basic concepts through a wonderful explanation and visualization. Thank you Sir for explaining
Thank you Disha. Yes, I've been through that too when I was a student. That's why it was important for me to post such a video. I am thrilled that I was able to help. Thanks for hearts. Here are some from France ❤❤❤ :-)
Hi Shahare, I am glad you enjoyed this video. I 🧡 thermodynamics, I think it is really a fundamental pillar of physics. And, it is true I don't have many of these on my channel. It's on the list !
Thanks for the well explained and approach to know electrical field and electromagnetic waves, I am a chemical engineer but I found it it easy to understand such concepts Many thanks and appreciation prof
Hello Aymen, in chemistry the concept of electric potential is really central in order to understand the interaction between species. All the interactions in chemistry are related to the charges these species carry, and how these charges are distributed in space. So I am really glad my video clarified a few things for you. See how this applies in your field of expertise!
Hi, Thank you for your kind words. I am glad my video helped you understand such an important concept. Now you can enjoy exploring deeper, there is a whole world of electrical knowledge that awaits. :-)

It was superb.......I had understoood in a such a way.....THAT MY MIND BEFORE WATCHING THE VIDEO...AND AFTER WATCHING THE. VIDEO....😉
sir i got confused on this topic since 2 moths and i tried to understand the concept but i can't understand , finally today you have clear my all dought , thanks a lot
Hi Shambhu, I love reading these kind of comments because these reflect the exact objective I set for making these videos. Thanks for letting me know! It makes my day :-)
I’m an undergrad taking electrodynamics, and after this video I FINALLY have a grasp about the potential! I honestly had a better grasp on electric potential than gravitational potential, which always confused me when it came up in classical mechanics, such as the explanation for Lagrange points.
Hello Joshua, thank you very much for letting me know.
This type of comment hits the right spot about why I created this channel!
Amazing video finally got a hold of what potential really was after studying the entire electrostatics!This video really helped clear those concepts.Just had a small doubt..why do we define potential as the work done in moving a unit positive charge from infinity to that point?
Hello Mayamo... the definition of the electric potential is kind of a the starting point...
It is the energy per unit charge that an object has when placed at a given position. It is therefore equal to the work that has to be done on that object to place it there...
@@PhysicsMadeEasy But according to the definition, you would have to bring the object there all the way from infinity, right? And that is equivalent to the area under the graph that you drew (assuming there are no other electric fields on the way to the destination). I am just trying to wrap my head around this infinity thing...
This channel is probably the most underrated channel right now
Thank you Aman, You know, I do not need to be overrated haha! As long as I unlock understanding blocks in many students around the world, I attain my goal.
Awesome you are the best communicator I have met and I am a professional civil engineer, but had difficulty understanding voltage. Thank you very much.
Hi there, thank you for your feedback.
I am glad I could clarify this for you. By following rules, you can always manage without really understanding the physical concept behind voltage (tbh, I went through a large fraction of my uni studies that way).
Maybe you can go back into passed projects where this concept was used, and see what you could have done better. I certainly did when I finally got it!
Finaalllyyy understood this…..ive spent literally 3-4 days just on this topic…..feeling so good now!
Thanks Kushrov for letting me know! I am super happy that my video had this effect on you!
Lucid, direct and clear explanations.
Something to note about a common point of confusion is the difference in nomenclature between the concept of energy and work.
This really helped to make that difference stridently clear and really helped to tie it all together
Thank you Dr. Reny🙏
Thank you Mello Cello for these encouragements! I am glad this video was helpful to you!
Best video i have watched so far about PE. No video made me understand about it, except this video. Thank you very much sir
Hi Paradox. You are welcome, and thank you for the encouragement! I am glad it helped you unlock the understanding of such an important concept in physics!
I'm in uni and I've been dealing with these notions for years and it feels like I've never really understood them until now. Thank you so much what a great teacher!
Thank you Marie for your very kind words. If my video brought you a new understanding, then dig out your old school and Uni notes related to electrical sciences, especially those you are still fuzzy about, and rework them with that new understanding...Haha moments await you :-)!
Dear Dr. Reny, I really appreciate the quality of and effort behind this video ranging from the animations and intuitive explanations to even the changes in location while explaining said concept, as a student this really helped me grasp a vital concept i was unable to before. I thank you very much for making this video.
Hello Tango. Thanks you so much for your wonderful comment. I am glad my approach helped you understand and assimilate such an important concept. Review your previous class notes (those you took before you understood what an electric potential was), and reconstruct them based on your new understanding.
Be ready to get crowded with 'ahah' moments :-)
@@PhysicsMadeEasy i sure will sir!
I love you man. Thanks a lot, I wonder why our teachers don't explain this concept like you did in classrooms.
I wonder too... My channel is kind of a reaction to the hard time I had in High School. Still they exist: some lucky students are exposed to such teachers (I had some at Uni that took the time to make me bloom, and they became my inspiration)
You're really really great sir!
I'm undergraduate degree physics student and I was struggling to understand the concept "potential" in physics.You just made it clear for me.
I want to be great teacher like you who can make things clear for others.Thank you sir🙏
Hello Adane. Wow, I am so proud if I can inspire you in taking a teacher's career. It's one of the most wonderful jobs in the world. Actually, I was inspired during my undergraduate years by a teacher in electrochemistry (A topic at the time I hadn't understand). He was a little rough with us students but he was precise and clear. And when things are clear, the subject can now become interesting! That made me want to be like him (even if I am a little more patient with my students than he was, haha)!
With you wanting to become a teacher too, maybe the circle is complete :-)!
@@PhysicsMadeEasy in the same way as your electrochemistry teacher inspired you, I'm really inspired by you and I'm sure you are and will be an inspiration for many.
I love the way you explain things and thanks sir for give your time to reply and for your every lecture videos 🙏
Nah man, we all owe you quite some appreciation for your wonderfully explained video using simple analogy. Hats off to you!
Thank you Ahnaf, I am glad you enjoyed this video!
I'm 27 and some how managed degree and job without understanding much physics but a part of me always want to understand how everything happening around me, thank you sir.
Hi Chandler Bing :-) !
I am glad my work helps you make sense of things!
Amazing!
I‘ve tried to understand the voltage so many times through other videos, but you are the best I fully understand the voltage. Thank you so much.
I am really grateful for your feedback! You just expressed the reason why I have created this channel ! ❤
Amazing explanation and even more amazing visuals. Superb content. Please continue doing more physics videos! It is a massive help to students like me who self study!
Hello Malek, Thank you very much for your kind (and motivating) words. I will try to find some time for that. And I am super glad my work does help so many students around the world. Good luck with your studies!
Great visuals! I had never had this easy time in grasping concepts like this one. Keep up the good work sir!
Thank you Jitendra, your words are very encouraging!
hands down the best explanation on the internet.
Thanks Mitch :-)!
you are so good that I can cry. I'm have been watching videos for months about voltage. You are the best
Thank you for these very encouraging words! I am glad the videos helped you in understanding electric potential and voltage.
It Is unbelievable to see a professor like you
I wasn't able to understand this as in India as many comments say don't have that good professors/teachers
But Today I finally Understood the Concept Each Bit :D
Another surprising thing is you are actually clearing doubts of Each guy in comment section as well !
Subbed and Liked The Video Sir
Thank you Niko! your comments show that my work on RUclips is reaching the goals I set for myself :-)
@@PhysicsMadeEasy welcome sir
Hi sir, I am currently doing my Master in Electrochemistry and after watching this video I realized that until today I did not know what actually electric potential was. I am eternally grateful to you, keep going!
Hi Medina, thank you for your comment.
I studied some electrochemistry at Uni, a hard topic but one I enjoyed because of it being so borderline between Chemistry and Physics. Then, when I worked as a researcher for a large company, I used my free research time to create an electrochemical lab because I was interested in looking at the impact of chemically induced films (oxides or organic) for the corrosion inhibition on various metals (in pipes for example). I was quite successful at it.
The strange thing is that me too, I did not have a good understanding of what an electric potential exactly is. I had made my own idea, close enough for what I was doing, but when I reviewed the school physics programs before starting my teaching career, I realised I hadn’t really understood it. I wish I had, because it would have made me much more powerful in my research: I probably would have won a Nobel prize lol!
I also realised that not many people do understand electric potentials. A friend of mine is an experienced electrician, working in that field for years. He worked the electricity of my house ( I paid him for that), One day, I asked him, what does 9 volts means… He only knew the water analogy, but not the real meaning…
So your comment did strike a sensitive chord: I am so glad I made you more powerful than I was. This makes me shiver as a teacher:-) !
Good luck and I wish you much enjoyment with the study of this great subject!
The way you explained everything was just incredible. I am so glad I found your channel. Thank you!💙
Hello Ada,
Wow, these are encouraging words! thank you,
I hope you enjoy the rest of your voyage on Physics Made Easy airlines!
Best Explainer video I have watched in my whole life. Kudos!
Thank you Nana!
Out of every video that I saw, this is the best explanation so far for the concept. Keep the great work sir.
Thank you so much for your kind feedback! ❤
Sir
I opted out of by graduate of electronics and communication engineering course because
I was not convinced of what I was taught
This is the first time in last 31 years,that
I have understood the concept of electricity from your tutorial.
Hats off to you
God 🙌 you!!
Hi K.G. this is one of the most heartwarming comments ever, Thanks!
It's a shame you didn't hold on to your graduation course. Often, specially at the beginning, it is necessary to just accept what is taught. Then, with time, the brain connects the dots, and things get clearer.
Still, you chose another direction, and you may be fulfilled with it today, so no regrets! You can always continue studying physics as a hobby!
@PhysicsMadeEasy
Thanks
I choose financial management &
Work as an analyst.
Nevertheless,
I keep updated on technical learning.
Your videos unlock the cause & effect,
Which is how physics should be taught.
@@K.G.Thyagarajan And do you know what is one of my hobbies? Asset analysis (for myself only: building up my retirement) 🙂
I'm glad I discovered your channel. Thank you for taking the time making these for us.
Omg, this concept gave me a headache when I tried to listen to the lecture of my professor. On another you explained this in an extremely easy way to understand. Thank you so much sir !!!!!
Hi Sang, I am glad my work helped you unlock this crucial concept for you. Electric Potential It is not a concept that is difficult to grasp, but it can be a pain for students if not explained properly. And this is why I created this channel!
Good luck with your studies of Physics!
Excellent explanations of electric potential and electric potential energy. The concept is simple but for some reason I get them confused. Now the fog has cleared and it makes my understanding of electronics easier.
Thank you for telling me this!
This kind of comment is one of the reason why I have created this channel: To help girls and guys like you lift the mist that hinders the understanding of some basic concepts in a topic that you are passionate about.
Enjoy the clearer skies!
The video just keeps getting better. Thank you sir
Thank you for your kind words :-)
I'm loving this series. I needed it so badly
Excellent, Fantabulous!!! No one would've ever explained in this manner. Thank You!
Hello Sriram, thank you for the compliment :-). I am glad you enjoyed it!
this is the best explanation i've ever had
Thank you Sarah!
Best best the best and great.i bow my head on your explanation.its taken me 15 years and you solved in 5 minutes
Thank you! When I started teaching, I realised students had no clue about what is an electrical potential. They were just getting buy by applying the rules. I actually asked an electrician, friend of mine, that I employed to do some of the electricity in my house, he actually didn't know exactly what it was, just how to handle it in his job.
I said to myself, I need to do something about that!!! Hence this video.
I am glad it was so helpful to you :-)
Omg can't thank you enough!!!! You've no idea how helpful this is.❤
Hello Fariha, I am so glad my video helped you with your studies. Thank you for the feedback, it encourages me. ❤
The most underrated channel of all time.
Thank you! It's probably because I do not like having ads on my videos, thus, they are not promoted by youtube (Although I heard RUclips is going to force it soon)! Don't hesitate to share the channel link or the videos, so that others can enjoy some Physics fun!
Thank you so much for taking the confusion out of these important concepts. 🙏
Yes, understanding electric potentials is crucial when dealing with all electrical sciences. That's why I made this video. I am glad you appreciated it :-).
This helped a lot. I've been searching for a good explanation of electric potential for a lot of time. I couldn't wrap my head around the idea that a bunch of charges of a battery have a potential. But this video explained that it's more about potential energy that these changes are "making" with their field's.
And thank you!
Yes, charges do not have a potential. They are positionned at a location with potential, but themselves do not have potential. Because they are positionned at a location with potential, they get potential energy (work was needed to bring them there).
I am glad it clarifies things. Still, can you rephrase your last sentences so I can check that you really got it?
Potential energy is a property of the charge, and potential is the property of the point at which the charge is placed, right?
@@learningisfun889 You got it! 😊
thankyou so much sir i was studying electricity from last 2 months but still wasnt able to understand potential very well you really helped me a lot
I am glad I could help Parinit!
i ve never understund the electric potontiel until i watched this incredible video thank u soooooo much
Hi Simbaland, you are warmly welcome. It makes me happy to have helped you understand such a fundamental notion. Now enjoy all the other understandings you can explore from the concept of electric potential. :-)
The best explanation I've seen so far
Thank you for these kind words :-)!
Thanks sir for clearing my concepts
You are welcome Hariom :-)!
Interesting videos!!!!! Very helpful, you are now my favorite RUclipsr!!!!
Wow! thank you for these encouraging words! :-)
best explanation I have ever heard or at least remember! Thanks
Thank you for you feedback Leo!
I got my answer here, awesome video. I have been searching for it in many videos and finally I reached here.
God bless you Sir✨
Thank you for letting me know: I am glad my work helped you!
dude thank u sooo muchh I was literally struggling with it from class 10 you just made it crystal clear 🙇♀🙇♀🙇♀
You are welcome Deep. Glad I could help.
Thank you for this video, it really made me better understand electric potential (EP). There is one thing I don't get - according to the EP definition, you would have to measure the energy spent to bring the positive charge all the way from infinity to the point of destination. Wouldn't that be equal to the area under the graph you drew? Also, how about other electric fields that the positive charge might encounter along the way? This infinity definition is kind of hard to wrap my head around.
Hi Narnia,
The idea of infinite distance from the charge source of the electric field is a conceptual idea… If infinities bother you, you can change the definition to: an electric potential at a position is the work required to bring a charge to that position from a point where that charge is not under the influence of any electrical interaction.
No the PE would not be the area under the graph… Because V=kQ/x, the area under the graph would be a quantity proportional to the charge creating the field.
When you have these kind of questions you can also check units! The area of a electric potential-position graph has a unit is J/C multiplied by meters, so not that of an energy.
@PhysicsMadeEasy Thank you so much for your comprehensive and kind response! It helps me understand better. We can basically choose the reference point anywhere, and define that the EP there is 0.
And yup, I see now that my statement about the area makes no sense :)
@@narniabusiness7810 Yes. The reason why we place the charge at infinity is because of Coulomb's law (inverse square law with distance). In reality, whatever the distance between two charges, there will always be an interaction, even if extremely small. That is why we need infinity to make that interaction zero within the context of an absolute definition (a definition, by definition (punt intended;-) ), cannot contain approximations).
@PhysicsMadeEasy Truly thank you man, you're awesome!
You are amazing, Sir!!!
i don't know why your channel is so underrated, i think there is a bug in youtube algorithm...
Thank you for your encouragement :-). But you know, for me, as long as the videos end up in front of the eyes of those that need them, I'm good :-)
@@PhysicsMadeEasy thats nice
Great video and explanation!
It was absurd for me what Electric "Potential" is, when I was introduced to it
You made it so simple :) Thank you very much
It was the same when I was a kid. I had to fix that :-)!
Thank you very much for making hard concepts simple to grasp.
That's the goal of my channel! I am glad it works!. Thanks for the kind words naayou ❤
Sir your teaching is great love from India
Thank you Aryan :-)
Incredibly helpful and clear explanation, thanks sir.
Hello Cala, you are welcome and thank you for the kind words!
This was so good! Finally my understanding of electricity is clear! Thanks to you ❤ keep making these gems ❤
Cheers Augliyot. I am glad you made the best out of my work! Good luck with your studies!
Thank you so much for making this video, it made it very understandable and easy to grasp the concept.
Hello Suzana,
Glad I could be of help :-)
You are absolutely brilliant. I am going to share this with my teacher as a studying aid for future students!
Thank you Mareena, I am glad you find my videos useful: It's the whole goal of my channel to help students that are struggling with these concepts. I choose the topics just by observing my own students... Please feel free to share with anyone that can benefit from these!
thanks sir, you are a gem in teaching physics concepts
Thank you for your kind words! I am happy my videos help you in understanding fundamental concepts in physics.
Thank you so much.... I never understood this concept clearly in the past. Thank you for this explanation
Thank you, I am glad I could transform super brains into hyper brains ;-)!
thank you sir!!!🙏
before this video I'm confused about electric potential and voltage but after this videos it become very easy to understanding this for me
You are most welcome Herman!
Thank you so much sir!! I couldn't understand this topic since 9th grade and now I'm in 12th, you really made this topic easy😄😄
Hello Roy, that's fantastic: it is for this kind of result that I made this channel (I was in a similar situation as a student). Now, go back to your class notes about electricity, and read them again with this new understanding. Like pieces of puzzle, they should start to make much more sense :-).
That was smart of you to move to an outdoor setting in this video. It gives a sense that you are more human and keeps the listener involved.😊
Hey John, thanks for noticing :-).
Indeed, it gives a little air, to have these little interludes outside where what was seen is briefly summarized: It makes it more pleasant to watch, and in the end, might stick better in the viewers head. I should do this on more videos!
Amazing video! You really helped me understanding this concept
Super, goal attained! Thank you for your feedback ❤
Very well made and insightfull videos on mundane concepts of physics, thanks !
Thank Rajesh! More than mundane, critical!
@@PhysicsMadeEasy Yes ! Absolutely foundational concepts.
Thankyou so much. You're indeed a saviour for me, i had been struggling with solving those questions I had while studying the concepts from weeks. While some are left, this was very beneficial for me. Thankyou.
Hi Angu, thank you for letting me know. I am really glad I unlocked some concepts for you. So yes, good idea to jump back to your old notes and exercises, and see how these make sense now!
Really need you as my physics tutor for iit jee indian examination one of the world toughest examination. Please upload more such videos. I watched many professor videos like walter lewin, prof carlson, and many more others. List is huge i could never understood this term properly. But watching this 8 minutes video i felt like how easy physics is you just need a good tutor
Thank you for your very kind words. I am glad that my work helped you out.
With all my students, I very much insist on a good understanding of the basics: Bright students can manage without sometimes, by just using the rules, and mimicking standard exercises, but sooner or later they become limited in their ability to understand more advanced concepts and can lose interest in the topic, although they would have become amazing physicists otherwise...
You explained every bit. I was struggling to understand this concept. I am a Class 10th student from India 🇮🇳. Thank You! Subscribed😄
Thank you Anand! I hope it helps with your studies. All my wishes of success!
I have been scouring youtube as I try to catch up in my physics class. You have got to have some of the best explanations I have seen. I loved your analogy to gravitational potential energy as it really cleared everything up for me. I cannot tell you how sick I am of the goddamn water pressure analogies lol! Thank You!
Hi Diego, the water analogy... me too!
I do use it for the lowed grade students that do not understand yet how to manipulate the concepts related to energy, but I do tell them that they will have to fade it out once they get a better understanding.
Thank you for your encouragements!
I really enjoy your videaos; need to watch them several times to grasp it.
Hello Steve,
That's the spirit! Explaining these concepts in 10 minutes can make the video quite intense... I am really glad you are making the most of them by viewing them multiple times.

Hello Aymen, in chemistry the concept of electric potential is really central in order to understand the interaction between species. All the interactions in chemistry are related to the charges these species carry, and how these charges are distributed in space. So I am really glad my video clarified a few things for you. See how this applies in your field of expertise!
