I really love the video! Please make video about transformer, why transformer primary winding dont have current when there is no load in the secondary windings!!!!!! Tnxxx....
@@Rod-l6jif you power up a transformer and there is no load on secondary, there is still some very small amount of current on primary cause by the fact that the wire is arranged in a coil shape and there is a feromagnetic material inside the coil. If you'd take that same coiled wire, and straighten it out, and try to apply voltage to it, the result would be completely diferent.. You would end up with a short circuit.
I've been watching a lot of RUclips videos on electricity the last few weeks and this video is one of the clearest explanations on the whole of the internet. Thank you!!
In 1966 while pursuing a BSA Radio Merit Badge at age 10, I became involved with the Navy Military Auxiliary Radio System (MARS). All that to say: I had to learn all the Electrical Formulas by rote. Any young person today interested in Electrical Engineering will be well served by your excellent presentation. Thank you for not “dumbing down” the subject in any way.
So this video, while being one of the better ones I've seen on the topic, is oh so close, but I think it still leaves a common misconception about what is happening in an electric circuit. There are several hints in the video about this, especially starting with the field discussion at 6:53 and the drift speed discussion starting at 8:10. I'm not saying it is wrong, but rather that a key idea is missing. This idea becomes clear in an electro-plating or electrolysis situation where not just electrons, but whole molecules are caused to move by the current. The drift speed and time differential in what happens was covered quite nicely by Derek in a video on his Veritasium channel. I think it would help to say that the ENERGY in an electric current is a wave function that travels along the surface of a conductor whose electrons (or molecules) are easily pulled free to move in the direction of the current. Thus, the motion of the electrons, while fitting quite nicely with all of the math and equations, can better be thought of as COMSUMERS of the energy in the current. This makes the pressure discussion in the light bulb explanation more obvious I think, and it totally accounts for the delay in their motion when a current is first setup, It's a drag function.
@@charlemagnesclock Dereck was wrong, we know this because wire gauge is an exceptionally poor way to gain surface area. By that proposal, smelting common copper (as 110v electric grade) and placing it into finer gauges would increase the ability to carry charge and it doesn't
@@kabbak This is a guess, but I think it is a good one. So let's look at what the physicists are telling us about the nature of particles when they come together and form larger structures such as atoms and molecules. This thing they call are still calling forces (now down to three, since they have decided that gravity isn't a force) is somehow a kind of energy that has the potential to bind things together. Remember that all of physics, especially at this level, is just math, models, predictions, based on those models, and measurements to validate or find issues with the predictions. So definitions for things like forces and energy start to look more like equations than something to which language structures like to assign something discrete like a noun. Every time physicists start to get comfortable with saying something IS x, some new data comes along to cause trouble for that sort of statement. Ok, with that serious limitation in mind, it would seem that way down at the particle level, there is some sort of similarity between energy and the three remaining forces. As temperature goes down, the energy level within the particle structures goes down as well, especially as things approach absolute zero. Thus, one would expect the drag on the waves travelling along the surface of the materials that easily let go of their outer shell electrons (i.e. conductors like copper and gold) becomes even less, hence superconductivity. This line of thinking would seem to align well with the challenges that have been faced trying to identify a way to have superconductivity at STP. But again, I would rather put the question to someone like Sabine Hossenfelder or Angela Collier, since they are real physicists, and are both good at explaining stuff like this. And I am fully open to Angela having one of her little snits and calling all of this crackpot physics. Derek Muller is more of a math guy, but because of his channel popularity, he has the ability to tap a lot of top physics teachers to make contributions, so he could do a good job as well. And while we are at it, let's all wish Dianna Cowern success in her efforts to recover from long COVID.
i'm 100% with your thoughts, sevensexton (below)!! i'm 68 YO, trained in electronics 6 years,RAAF, electrical contracting 45 years. Knocked heads with two eelectrical uni professors and many electrical engineers, none of which wanted to or could explain this electron drift concept, clearly.I feel that I have only 10 years of brains left to clear my thoughts on this subject. The complex interaction of magnetic fields inside a switchboard when high currents are flowing and cables are tightly bundled, is mind blowing. Insulating voltage is a whole different ball game to insulating magnetic flux, which is the science of electromagnetic propergation through the ether, where the energy literally leaves the wire. I hope your head hurts as much as mine. My wife and I made two electrical engineers and one RNurse. That took 30 years, but I thank you, with all sincerity for your 2 months on this video. Very well done!
All I can say is Thank you! I've been studying electronics for years with varying levels of intensity and practice. This video made its way into my head in a way that nothing else has. You titled it ' for visual learners' . I'm going to explore how that method might help me more. I've been a technician and could spout out whatever was required to accomplish the job but I've always felt that I never fully ' got it' in terms of knowing these things "in my cells" like I comprehend subjects like music. This may sound odd but this video has released a kind of intellectual stress I've had on this subject. Keep doing this wonderful thing here!
If you only knew how happy it makes me to hear that coming from a somewhat professional in that area. I always thought that I was simply too dumb to understand electricity. And don't even get me started on how radios work. It seems my brain refuses to understand anything it can't see...
At first when I saw the Veritasium's video about the propagation of electric fields a while ago, it blew my mind, and I didn't quite understand it. Then, he made a second video and I understood it a bit better. And after seeing this video I'd say I understand it even better. This is a very interesting topic that most of the general public don't know about, and I think it should be taught more. Very good animations and explanations, great video! Thank you!
I saw that too, and it’s interesting to think about. Wherever there’s current, there’s magnetism, right? What EM said here about the electrons wanting to expand away from each other, forcing themselves toward the conductor’s surface is interesting. But that’s a separate behavior.
Nice to see a video that highlights the role of surface charge in circuit theory. For too many years it has been neglected in basic courses, to the point that ignorance of its role is a major cause of misunderstanding electrical phenomena. I envy your ability to synthesize concepts in so short a video. It's taking me multiple half an hour videos just to introduce the concepts of voltage and potential difference.
Absolutely! The discovery and harnessing of electricity were truly revolutionary. Those scientists were like real-life wizards, shaping the modern world as we know it!
Very refreshing (no pun intended) to hear someone attempt to actually explain electricity -instead of just using the "water-flowing-in-a-pipe" analogy. I'm still not desperate to understand how it works, and watching this video a few more times should help a long way!
@henkenheimer9034 most of the people explain electricity as just saying water flowing down the pipe in microscopic version 😅. But this guy explained everything in a proper way
Ohms law is not a law that ohm created but an order which things obey which ohm happened to witness. Who gave the order and why are the things so loyal as to obey consistently? You see different perspectives look for different ways to explain things. Water through a pipe is perfectly fine.
@@LetYourMindPlay Until it's not. Last time I checked reversing the flow of water in a pipe 50 times a second did not help it travel further. The comparaison with water is really just that, a comparaison. It can help explaining electricity at a very very shallow level, but too often that's the only explanation we get. It's like saying planets are round because they "prefer" this shape, which I read somewhere. Just feels very unsatisfying and illogical.
As a newly licensed engineer trying to better myself in the field I just wanted to say thank you for all the great content! I am constantly watching your videos at work and taking notes to try to teach myself a little more each week. Appreciate all the great content!
Where was this video when I studied electrical engineering. This is a superb video for people like me who struggled to understand the dynamics of electricity.
I just started working at an Engineering Company and I found this super helpful! I am only an admin now, but this is definitely a step up when the Gents talk about all those electrical terminologies that idk. A handy electrical engineering for noobs like me!
I feel like I'm a pretty handy guy around the house. Except when I work with electricity. I get shocked every time. I am most definitely a visual learner. This video is the best I've seen.
this is the most deep dive of electron(ic) concepts explained in the model that electrons are visualized as individual objects. the new perspective helps me quite a lot
I love the depiction of the free electrons in the copper wire, simultaneously bouncing around between the valence shells and submitting to voltage to participate in a current.
After watching a number of videos on this topic, including the discussion between Electroboom and Veritasium, etc... this video is the one that has brought this modest mind to a closer understanding of what's going on in a current carrying electric circuit. Thank you!!!
This was a great deep dive on how electricity "flows." It not only corrects the conventional laymen's wisdom we learn in grade school (and even during some undergrad courses) but it makes something that sounds so unintuitive when you first hear the concept much easier (it's still not a walk in the park 😂) to wrap your head around! The animation and the script to make this video must have been a ton of work and research so I very much appreciate the effort; thank you.
I used to skip the chapters related to this subject during my study period for not finding it interesting. Now, you just making me like it. Thank you for the efforts you put to deliver knowledge for free.
Thank you for this! I largely slept through most of my physics classes in high school because "when am i ever even gonna use this stuff??". Well I sure ate my own words with that one because now I'm a student pilot and have been really struggling with understanding some of the electrical systems on an airplane, largely because I didn't have a fundamental understanding of how electricity works to begin with. So thank you for giving me that solid foundation to build upon
At 8:21 the correct formula to calculate the Time to travel should be time=distance/speed, not time=speed/distance. The result is correct, but the operands are swapped. Great explanation though, thanks!
@@EngineeringMindset While we are at it, at 4:00, the formula for power should have amperes (units) squared, so 5Ω × 0.3² A² = ..., or (0.3 A)². An excellent video packed with valuable condensed information!
I started following you Evans. I like your videos and I teach Air Conditioning from an engineering perspective. I am fascinated by mathematical formulas. It is wonderful when one demonstrates a natural phenomenon with the result of a mathematical operation. Excellent.
The visualization of electric field lines at 6min14 genuinely blew my mind and gave me a real intuitive understandings of why magnets attract or repel each other
We need more visualizations like this. There is no such thing as "visual learners," we all learn through visualization of images, as sight is our main perception and how we explore the world. If you learn by reading, you are taking the words you read and converting them to visualizations too.
@@AshyLarry99 You've got me wondeirng what if you were blind from birth and touched a cube. I guess the tactile profile of that object isnt able to be translated to a visual spatial image. So how do they traverse spatial environments through touch alone? How do they remember where the doorway is and where the food is? I suspect they still somehow visually construct things through imagination. Is your visual cortex still able to visually hallucinate any simple shapes or artifiacts like when we close and rub our eyes?
Perplexity says studies suggest people blind from birth integrate information from the other senses in the occipital cortex which is usually used to integrate visual information. I believe the evidence suggests the Universe is made entirely in the imagination of consciousness as the transformation of the unseen cause into what appears to be as the video demonstrated the arc that appears is not electricity but the appearance of it's effect which is entirely dependent on object used to detect what is fundamentally vibrations and transform the information it receives into an appearance for observation. Einstein said imagination is more important than knowledge. I think because he knew that all knowledge is made entirely of imagination which is the transformation of the unseen cause into what appears in the world as is stated by his theory of relativity E equals MC2 which would be more correctly stated E appears as MC2 or energy appears as everything. I've seen and agree that E equals MC2 should be put in brackets with an exponent of infinity. What's amazing is the scriptures of every major religion agree the Universe is made entirely of imagination in different words not withstanding that the sects of religions say many different things some of which are obviously not true but that doesn't change what the scriptures can objectively be viewed as saying. For decades I've told religious people in my family that I'm not going to believe anything that can't be shown to be true by evidence even if the evidence is necessarily outside of the scientific method for determining facts because the fundamental truth of the Universe can't be proven objectively because of the fundamental truth of it is that the Universe is entirely subjective. Our Universe would be absolutely undetectable from outside of it because it is made entirely of vibrations which can be only be "imagined" by vibratory systems which are related to the vibrations they receive because otherwise there is no template by which to use as a comparison to determine the value of what is perceived because as E equals MC2 says everything in the Universe can only be defined by it's relativity to everything else in the Universe. A person blind from birth can't see anything, according to Perplexity AI, because they have basis of relationship. Another amazing thing is how the words chosen by the most accomplished scientists that are used to identify things in science so often have cryptic messages in their structures when viewed etymologically and or syllabically such as the words Phospholipids, cytoplasm, ribosomes etc.. Biology comes from the Greek bios meaning mode of life and logos meaning word. The word in the Bible means electricity as in the beginning was the word. Cytoplasm means the word across the waters. Phospholipids form the boundary of our cells and are a firmament that separates the waters from the waters which are what are used to identify the end of one thing in the Universe and the beginning or edge of a different kind of space in science seen as things like pressure differentials like the edge of space or the eye of a hurricane 🌀 or the edge of a hurricane with all of these boundaries having different degrees of preciseness because there are no completely closed systems within the Universe because every part of the Universe is dependent on every other part. I forget I'm commenting and go on and on. 🙄
This is genuinely an amazing video, thank you from the depths of my heart. As a kid everyone chose to learn through equations and didnt bother with what you explained. I always wanted to see what was happening at an atomic level and never got to see it until now. I learned so much more and I'm studying to become an electrical engineer, youd think they would teach us things like this. Genuinely, thank you for this amazing video, I never thought I would be able to see such a brilliant educational video for free too. Question: when an electron is removed from the wire by a battery, why would electrons redistribute towards the middle instead of equally throughout the disc?
Thank you! This video is fire, it explained the basics better than my High school physics and also delved into the "electric fields - electrons moving" relation which we rather avoid in school because it is seen as complex. Great work, I love it!
I've always been a bit confused about whether it flows from positive to negative or vise versa, this is the first time I've completely understood why and how this works like it does. Thanks!
I LOVE learning new stuff and this videos did NOT disappoint. I’m 3 minutes in hearing about coulombs and 6.2 quintillion electrons per second. Good Lord, let me rewind now and absorb it properly!
Your videos have always been very helpful while I was taking classes in university, and even now as an entry-level electrical engineer. I would recommend doing a video on motor control centers and switchgears!
for the first time in my entire school life,I was able to understand electricity and it was only possible due to this video.... THAMKSSSSSSSSSSS!!!!!!!!!!!!!!!!!!!
Amazing video! Making such a difficult topic easy to understand is such a difficult task but your animations and explanations were top notch! You should be proud of yourself with how many minds you have now helped to expand and how many more you will in the future! Thank you for your efforts.
Hi, thank you for your video. I've always had problem with understanding how electricity in general works and I couldn't understand it even when everyone tought me same things about water and pressure and how it is similar to electricity... But I really needed this type of practical and visual teacher. Now I understand basics of electricity and I can build on it. Thank you for your video.
For those of you confused about “voltage drop”, it’s also called “potential difference” and it’s always between two points. That’s why there’s little “voltage” along a copper wire: little resistance means little difference in potential. I’m still a noob so hopefully that’s right, but knowledgable people have said that “voltage” is not a good way to think of it because it’s not some kind of quantity, it’s a comparison.
I found this video from the link in your original video. I went to the comments after seeing your representation of electron fields. I just wanted to say well done on describing it more accurately in this updated video. 😁🤣👍👍
This video has explained most of my questions that I had 3 years ago, when I started learning about electric fields and also I am very glad that my reasoning turned out to be right 😂
I like this explanation that is very simply done but at the same time very complex and very accurate. I like the explanation using the electric and magnetic fields and its propagation along the wire by speed of light. Not many other videos actually mention that the electric field is not in the wire but around it😉
This is a really great explanation and I think a lot of people would have more interest in physics if they had teachers like you. I'm 46 right now but when I was 30 I wanted to finish my degree in engineering. In high school I flunked trigonometry, but in college I got an A in trigonometry because I had a good teacher and good resources. Unfortunately I was not able to finish because the people who give Pell grants, gave money so that I could get my associates in engineering and then move on. However the school said that I went over by 2 hours and instead of getting back a refund because I didn't buy any books and found all the books second hand or online, they told me I owed them $1,500. It's really too bad since I had good grades and an interest in the subject. It's sad how difficult getting an education in the United States seems to be. I salute you for helping young people to understand these things. It is a noble endeavor.
Thank you for this video. I am going to use this as a basis for my teaching. (16 year olds) Well, not so much the last part, but its good to have it, for those 1-2 students each class that have an affinity for the subject. Again, Thank you.
@@mind6861 Because they argued about what happens, and this video neatly summarizes the argument. Basically, Veritasium is correct but this video, that probably builds on his, is easier to follow.
Beautifully explained! i had chemistry class and they were explaining galvanic batteries and i couldnt understand a thing. but i came up w an example from this, its like a DAM, and when water is above the dam its positive charged, and released is whne the battery is working and it goes towards the negative which is down. and when the water is emptied wee have more negative than positive, so we have to work to put the negative back up to positive, then negative will never freely move to positive. but the positive is always wanting to give its water/electricity
BTW... side note: This understanding about electric fields makes me feel like I'm better equipped to attempt understanding again how A/C current can be delivered on one wire. (Though I bet a video from you would do another amazing job on it 😂)

I rarely write comments, but when I see the hard work someone is doing I have to say something. Thank you for the excellent animations.
I used to skip the chapters related to this subject during my study period for not finding it interesting. Now, you just making me like it. Thank you for the efforts you put to deliver knowledge for free.
That's literally why I followed you. You present content visually so well through animations it is incredible.
Easily the best simple animation and explanation for electricity I have seen. I’ll definitely recommend this video to my students.
Thank you for this! I largely slept through most of my physics classes in high school because "when am i ever even gonna use this stuff??". Well I sure ate my own words with that one because now I'm a student pilot and have been really struggling with understanding some of the electrical systems on an airplane, largely because I didn't have a fundamental understanding of how electricity works to begin with. So thank you for giving me that solid foundation to build upon
I've been looking for an explanation like this for the last 14 or so years since I finished university. Thank you!
At 8:21 the correct formula to calculate the Time to travel should be time=distance/speed, not time=speed/distance. The result is correct, but the operands are swapped. Great explanation though, thanks!
nice observation
You are correct, well spotted @davidegalilei e-mail me and I'll send you a mug.
@@EngineeringMindset While we are at it, at 4:00, the formula for power should have amperes (units) squared, so 5Ω × 0.3² A² = ..., or (0.3 A)².
An excellent video packed with valuable condensed information!
Thanks
Thank you!
Excellent explanation and presentation are understatements. You are an exceptional educator. Thank you.
i haven't studied this in a while, this was a great recap
I guess I am a visual learner, because this video explained shocking amount of my little misconceptions.
Thank you!
I started following you Evans. I like your videos and I teach Air Conditioning from an engineering perspective. I am fascinated by mathematical formulas. It is wonderful when one demonstrates a natural phenomenon with the result of a mathematical operation. Excellent.
The visualization of electric field lines at 6min14 genuinely blew my mind and gave me a real intuitive understandings of why magnets attract or repel each other
Explanation never taught in classroom awesome thanks!!
We need more visualizations like this. There is no such thing as "visual learners," we all learn through visualization of images, as sight is our main perception and how we explore the world.
If you learn by reading, you are taking the words you read and converting them to visualizations too.
not blind people
@@AshyLarry99 You've got me wondeirng what if you were blind from birth and touched a cube. I guess the tactile profile of that object isnt able to be translated to a visual spatial image.
So how do they traverse spatial environments through touch alone? How do they remember where the doorway is and where the food is?
I suspect they still somehow visually construct things through imagination.
Is your visual cortex still able to visually hallucinate any simple shapes or artifiacts like when we close and rub our eyes?
@@commonape856As a blind person from birth, no.
r/iamverysmart
Perplexity says studies suggest people blind from birth integrate information from the other senses in the occipital cortex which is usually used to integrate visual information. I believe the evidence suggests the Universe is made entirely in the imagination of consciousness as the transformation of the unseen cause into what appears to be as the video demonstrated the arc that appears is not electricity but the appearance of it's effect which is entirely dependent on object used to detect what is fundamentally vibrations and transform the information it receives into an appearance for observation. Einstein said imagination is more important than knowledge. I think because he knew that all knowledge is made entirely of imagination which is the transformation of the unseen cause into what appears in the world as is stated by his theory of relativity E equals MC2 which would be more correctly stated E appears as MC2 or energy appears as everything. I've seen and agree that E equals MC2 should be put in brackets with an exponent of infinity. What's amazing is the scriptures of every major religion agree the Universe is made entirely of imagination in different words not withstanding that the sects of religions say many different things some of which are obviously not true but that doesn't change what the scriptures can objectively be viewed as saying. For decades I've told religious people in my family that I'm not going to believe anything that can't be shown to be true by evidence even if the evidence is necessarily outside of the scientific method for determining facts because the fundamental truth of the Universe can't be proven objectively because of the fundamental truth of it is that the Universe is entirely subjective. Our Universe would be absolutely undetectable from outside of it because it is made entirely of vibrations which can be only be "imagined" by vibratory systems which are related to the vibrations they receive because otherwise there is no template by which to use as a comparison to determine the value of what is perceived because as E equals MC2 says everything in the Universe can only be defined by it's relativity to everything else in the Universe. A person blind from birth can't see anything, according to Perplexity AI, because they have basis of relationship.
Another amazing thing is how the words chosen by the most accomplished scientists that are used to identify things in science so often have cryptic messages in their structures when viewed etymologically and or syllabically such as the words Phospholipids, cytoplasm, ribosomes etc.. Biology comes from the Greek bios meaning mode of life and logos meaning word. The word in the Bible means electricity as in the beginning was the word. Cytoplasm means the word across the waters. Phospholipids form the boundary of our cells and are a firmament that separates the waters from the waters which are what are used to identify the end of one thing in the Universe and the beginning or edge of a different kind of space in science seen as things like pressure differentials like the edge of space or the eye of a hurricane 🌀 or the edge of a hurricane with all of these boundaries having different degrees of preciseness because there are no completely closed systems within the Universe because every part of the Universe is dependent on every other part.
I forget I'm commenting and go on and on. 🙄
This is a lot to take in, but this was animated so well so congrats for making such a good video.
This is genuinely an amazing video, thank you from the depths of my heart. As a kid everyone chose to learn through equations and didnt bother with what you explained. I always wanted to see what was happening at an atomic level and never got to see it until now. I learned so much more and I'm studying to become an electrical engineer, youd think they would teach us things like this. Genuinely, thank you for this amazing video, I never thought I would be able to see such a brilliant educational video for free too.
Question: when an electron is removed from the wire by a battery, why would electrons redistribute towards the middle instead of equally throughout the disc?
The light just came on in my brain, thanks to this epic explanation I now understand.
Thank you! This video is fire, it explained the basics better than my High school physics and also delved into the "electric fields - electrons moving" relation which we rather avoid in school because it is seen as complex. Great work, I love it!
I've always been a bit confused about whether it flows from positive to negative or vise versa, this is the first time I've completely understood why and how this works like it does. Thanks!
Duuuuuuudeeee!!! Thank you this is awesome!!! I will immediately usenthis in my classes!
I LOVE learning new stuff and this videos did NOT disappoint. I’m 3 minutes in hearing about coulombs and 6.2 quintillion electrons per second. Good Lord, let me rewind now and absorb it properly!
What a great video, with good explanations on concepts that many other electricity intro videos don't even mention. Bravo!
Your videos have always been very helpful while I was taking classes in university, and even now as an entry-level electrical engineer. I would recommend doing a video on motor control centers and switchgears!
Great video, love the visual effects, Well done , you’ve got a new subscriber!
Oh man this video is unbelievable! It introduced me to a new way of understanding electricity, nothing like Iwas ever taught before. Very cool
for the first time in my entire school life,I was able to understand electricity and it was only possible due to this video.... THAMKSSSSSSSSSSS!!!!!!!!!!!!!!!!!!!
Amazing video!
Making such a difficult topic easy to understand is such a difficult task but your animations and explanations were top notch!
You should be proud of yourself with how many minds you have now helped to expand and how many more you will in the future!
Thank you for your efforts.
The quality of this video is incredible. Nice job!
Omg this going to carry my asvab test
this channel is dear to me, im growing with it. another well done video. i wanted you to know that
That has to be the best explanation of this topic I have ever seen. Thank you.
Hi, thank you for your video. I've always had problem with understanding how electricity in general works and I couldn't understand it even when everyone tought me same things about water and pressure and how it is similar to electricity... But I really needed this type of practical and visual teacher. Now I understand basics of electricity and I can build on it. Thank you for your video.
This has been the most important information I have received..like you have been so clear
This is an amazing demonstation of increadble teaching ability. Very well done.
Thank you for putting the time in to produce this.
For those of you confused about “voltage drop”, it’s also called “potential difference” and it’s always between two points. That’s why there’s little “voltage” along a copper wire: little resistance means little difference in potential. I’m still a noob so hopefully that’s right, but knowledgable people have said that “voltage” is not a good way to think of it because it’s not some kind of quantity, it’s a comparison.
I found this video from the link in your original video. I went to the comments after seeing your representation of electron fields. I just wanted to say well done on describing it more accurately in this updated video. 😁🤣👍👍
This goes totally against everything I was taught in a genX public school 😮I’m rethinking my whole life because of this video!
The interaction at 16:25 is something I almost never see in a youtube video on electronics. Nice
This video has explained most of my questions that I had 3 years ago, when I started learning about electric fields and also I am very glad that my reasoning turned out to be right 😂
I like this explanation that is very simply done but at the same time very complex and very accurate. I like the explanation using the electric and magnetic fields and its propagation along the wire by speed of light. Not many other videos actually mention that the electric field is not in the wire but around it😉
It's in the surface layers!
This is a really great explanation and I think a lot of people would have more interest in physics if they had teachers like you. I'm 46 right now but when I was 30 I wanted to finish my degree in engineering. In high school I flunked trigonometry, but in college I got an A in trigonometry because I had a good teacher and good resources. Unfortunately I was not able to finish because the people who give Pell grants, gave money so that I could get my associates in engineering and then move on. However the school said that I went over by 2 hours and instead of getting back a refund because I didn't buy any books and found all the books second hand or online, they told me I owed them $1,500. It's really too bad since I had good grades and an interest in the subject. It's sad how difficult getting an education in the United States seems to be. I salute you for helping young people to understand these things. It is a noble endeavor.
FYI: The entire EE course from MIT is on-line FREE!
Perfection. Absolute peak. This has cleared up SO many questions. Thank you!
Finally someone simplified this understanding 🎉
Steinmetz equations necessary for electrical engineering.
Good channel 👍
Thank you for this. I've recently been interested in understanding electricity and this video is absolutely perfect.
I love the fact that you used water as an analogy. I found when I started EE the best visualisation you could get is water going through a pipe.
It’s good enough for most cases
Best video on this topic so far. I watched tons
I almost saw electricity from this video.. The best explanation i have seen in youtube.
Wow! THE SINGLE most helpful video on electricity for dummies I have ever seen!
Thank you! 🙏🤩👍
Explaining how electricity works has never been better. You did great
this is perfect thank you
You're welcome, hope you enjoyed
From the start, with flow from Negative,.. I'm like...Sweet!, this one is a good one!
Thank you for this video.
I am going to use this as a basis for my teaching. (16 year olds)
Well, not so much the last part, but its good to have it, for those 1-2 students each class that have an affinity for the subject.
Again, Thank you.
I am waiting for veritasium and electroboom to comment
Why is that?
@@mind6861 its a secret
@@mind6861 Because they argued about what happens, and this video neatly summarizes the argument. Basically, Veritasium is correct but this video, that probably builds on his, is easier to follow.
@InXLsisDeocan u put link to veritasium vid?
Thank you for this video! I have a BS in physics and still learned things from it! Quite a bit, actually.
Wow these videos are wonderful. Thanks for such great detail and overview. I also enjoyed the historical background. Great job!
Beautifully explained! i had chemistry class and they were explaining galvanic batteries and i couldnt understand a thing.
but i came up w an example from this, its like a DAM, and when water is above the dam its positive charged, and released is whne the battery is working and it goes towards the negative which is down.
and when the water is emptied wee have more negative than positive, so we have to work to put the negative back up to positive, then negative will never freely move to positive. but the positive is always wanting to give its water/electricity
Beautifully explained Sir. Though I have done my major in Physics but I learnt many new things from your Informative video.😇☠✌
Wow, this is real education.
Presentation 100 and well explained.Keep it up!
Dude, this was perfect
Kudos to veritaseum for first putting video saying electrons dont flow from one end to another!!
I'm considering becoming an Electro Technical Officer for the Merchant Navy, this video made me very curious as I never thought much about this topic.
Adorei a aula. Me fez entender muitas coisas e tirou várias dúvidas. Ainda me deixou com vontade de aprender mais! 👏
gosh im so thankful for this
Best of the best #Powerlearningchannel
Very nice video in-depth explanation of how things works actually in the circuit Excellent work ❤
BTW... side note: This understanding about electric fields makes me feel like I'm better equipped to attempt understanding again how A/C current can be delivered on one wire. (Though I bet a video from you would do another amazing job on it 😂)
