1st comment in fourth month
There is a reason why his videos are so effective. Ive noticed that his black background and light colours sometime create a photographic memory of the diagrams he draws. It helps understand all the concepts really good. I can imagine the motion in diagrams better in my mind.
No. This guy is fantastic. i finally understand this horror of electricity and electrical charge!!!!!
Very true
Somebody give this guy a raise, he’s helped out so much with physics..
i think this man was directly sent by God Himself
Come on bruh
whatvelse can it be
I think this man created god himself
Serious the man got a gift from heaven
@@alexchristensen9537 god cant be created, he has not beginning
I didn’t think anyone could talk about electric potential for 33 mins. Good stuff!
May the Lord be with us all that are trying everything possible to pass our exam's otherwise this man came to make things easier thank you so much God keep you in good health 🙏
This is so wholesome
Amen.
Ameen
I have never seen the teacher like you. I wish every teacher would be like you.
If so all students would be brilliant and scholars.
Words are very weak to express you. Because you are one of the person who made influence up on me to understand different subjects.
Thanks A lot❤❤❤❤❤❤
Have you read my mind? I've started studying about electric potential 2 days ago and you uploaded this video.
same lol I think most first year eng students are covering electromagnetism right now
@@ghislainr5127 same thing happen to me..i just searched
I'm not trying to ruin your moment of anything, but he reuploads videos quite often, including this one.
I don't know how to describe this man. I always refer to his video when I get something complex.You are really unique sir, thank you!!
I now completely understood the concept of potential energy. Wow! Thank you very much, JG.
Julio Gonzales, you are the greatest of them all. Shaping engineers into the real world. Thank you so much son.
Teaching way better information than the teachers we pay in school.
It's just that I can't reach directly to JG I owe him my academic life .since high school now am at the University. Your my hero man.👍💖💖💖💖💖

Tysm for your videos :)
Why???? I just had my electrostatic test this morning 😭😭😭. I wish I could watch this video 1 day earlier.
Thank you for being my professor in Physics for my entire college life
I'm definitely learning all on electricity from This channel...with This channel I'm confident I'm gonna pass my phs 102 this semester
did you pass?
25 years from now... I will show my kid this comment 😅.... Thank youuu
Hi, I am your doctor of urology. Sorry, you can't have kids
@@Simple436 haha I will let you know when my first kid arrives😂
@@Simple436 hello,I am your doctor of gender…I am fortunate to say that u r a confirmed Rainbow.
@@Simple436 hello, I am your doctor of geneticist and i'm sorry to say you're 95% a confirmed Horse
Please please do not stop the good work you are doing,you don't know what you are doing to the world
I found electric physics complicated and complex,but with you existing,you saved my life.
Oh my god. How can anyone be so perfect at teaching equally in math, physics, chemistry? this guy has my utmost lovreand respect
"By the way, you may want to take down these notes if you have a piece of paper"
Chief I'm on video 3/5 of yours that I have open on my browser I've been taking notes each and every step of the way towards my exam tomorrow, you're the GOAT
wow these videos are so helpful and make sense and are clear about everything you need to know
God Bless you man. I was so bad at grasping all the charge, current, amp, culomb. Now I get it. I am watching ALL YOUR VIDEOS.
This was posted exactly when I needed it!! Thank you
how u doing
Ever video of this Chanel inspire me to fullfill my dream.
As I want to be a chemist
Please can you do videos about normality of salts and redox reactions 🙏🙏
Thanks fo all you do!
think he has on his chem channel
Test on Tuesday. This helps a lot!!!!
For question 3, because the charge first decelerates from B to A, then comes to a stop, then accelerates towards C, wouldn't the total work done on the charge be positive, the potential energy be decreasing and KE increasing? Wouldn't it just have less work done on it (in comparison to part a) because the work done moving from B to A is negative but the work done from A to C be positive and greater than the work from B to A?
Honestly I would’ve been screwed without this man, the instructors in my school have all been trash. Calculus, Algebra, Chemistry, and Physics.
Everything you thought was all in my study materials word for word provided by my lecturer
I was watching while eating chips until minute (3:03) when I started taking notes. Thank you JG (((:
This guy seems to have a video on every topic I have a doubt in
For sure we are all STEM students here, hope we all achieve our dreams tho!! keep moving!
Hey . I'm here to thank you for being the BEST Awesome Teacher of this world
This is totally the best physics teacher you could ever have!!
Just the best of "BRILLIANT!!!!!"
Nothing really new terms, yet clarified all most all the doubts. It's is worth your 1/2 an hour rather than a full day of "change in kinetic energy"😃.
Sir,I don't just know but since I encountered your video I have been doing well in my studies unlike before
You are indeed God sent
Am a student of UNIVERSITY OF NIGERIA NSUKKA and I just want to say a big thank you
Thankuu so much , i have exam this morning, and im studying electric potential just this morning ❤
Your video are masterpieces . Thank you.
You're literally saving my life rn. my prof sucks lol
this mans the goat no cap
YOU ARE AWESOME JG TUTOR ! MILLIONS OF THANK YOU
I did charge transfer analysis on circuits junctions. I came to some theoretical conclusions:
The electrons are transferred in pairs only.
The number of electrons , on a closed dc circuit must be even.
Static electron, entering a circuit, in his frame of refference sees both the - and the +.
P.s
My eduction is not formal, so i dont stick to conventions.
Extrapulations mode suggest that there is something missing in the conventional way we treat charge. I cant put my finger on it , yet.
The convention of + and - is incomplete/ over simplified.
this truly came at just the right moment omg
Wish he talked more about the relation between electric potential and electric field
bro this man is saving my grades holy
I wasted so much time watching other videos trying to understand the difference between electric potential and electric potential energy. It put me almost a month behind in my Physics II class, and my test is tomorrow 😭 I found this video yesterday, and you did such an amazing job that I actually cried. I instantly got the membership and have been cramming ever since! I dont have much hope of passing this test with a great score, BUT I now have hope that I can catch up, and actually pass the class with an A or B. Thank you so much for all of the great content, and for giving me a fighting chance at passing my class!
Yeah same here I am a month behind as well. My prof doesn't really know how to lecture and uses the class time just for unnecessary stuff. My current grade rn in the class isn't looking good but I am still hanging on it and hoping to pass the class. :D Also, what's the update?
@TheOrganicChemistryTutor Does Phi mean Electric flux? Because Phi= E*A*Cos Theta (where theta is the angle between normal and electric field) Right? Thank you. P.S This question is based on the video of electric charges and fields.
Thank you so much JG in a country where my teachers don't really teach us wel.l your videos are the absolute best thing that has happened to me😫😫😫❤️❤️
Absolutely God sent
Concise and brilliant delivery. Thumb up 👍
This man has been a big factor in my academic comeback 😂😭
Electric potential difference is defined as the difference between two points in an electric circuit carrying some current as the work done to move a unit charge from one point to another
Does this make sense?
Wow, I havent seen a zig zag line as the circuit symbol for resistor since the 1970's, it brought back memories. The circuit symbol changed to a rectangle (in the UK) in the mid 70's!
HOW THE FUCK IS THIS GUY THIS SMART, he could probably teach every subject in high school and do a better job than 99 percent of the other teachers.
In the Pearson textbook it is written that Vab = Vb -Va, which is the opposite of what's taught in this video, I wonder which is correct, or if there is a universally correct way?
You Are The BEST!!!!!!💖💖💖
this is the best
my exam is tomorrow and i was weak on this subject
this really helped me out
thank you
You're the king of science! Thank you very much.
So good for sharing Physics knowledge. Thank you so much, sir.
شكراً لك❤
wallahi im finished i dont get it
Revisit the basics of E fields. That may help
Okay so simple
Electric potential( fuck wikipedia they're unreliable) is energy available to do work per unit of charge in an electric field.
Voltage is the difference in electric potential between two points, basically the amount of work that was needed to move a unit of charge from its position at the first point to it's position at the second point in an electric field.
what is the relationship between sign of the charge and the electric potential?
4:43 this is backwards, isn't it? V_ab is the voltage at A with respect to B. You would write the integral with "a" as the lower limit and "b" as the upper limit. V_ab is Vb - Va.
That makes me question a few things. Do people teach these terms differently?
Something dosen't make sense here for me...for number 4, the ke is increasing- makes sense. What doesn't make sense is how electric potential increased too... the formula is v=pe/q. This means that both PE and Ke increased, but that can be it. Can someone please explain ???
This is a godsend. Hopefully I'll make it this quarter.
You are a great teacher I am watched your some video you are great
Thank you so much! We are studying this in class right now
You're the best ❤
please what is the difference between electric potential and electric potential energy?
These terms are getting me confused 😕
by the way thanks for this you're a great teacher
I will be a senior soon , you helped me since year 8 in school! Thank you so much!🥹
you are the best forever
Thanks for uploading such valuable content daily!!😄
Love your videos
thank you for making this, although it's similar to my note lecture, it's still refreshing to watched it and learned more.. ❤️
Fantastic thanks
I love this man he saved my life multiple times
Man God bless u
can you make a video on work done in the electric field
Very very good video sir
Man I think I should drop out of uni and just keep up with your videos to date.
this may be a dumb question, but how will we know/tell if the displacement vector and the force vector go in the same or opposite direction?
I can't thank you enough!
Thank you a lot Mr if it were not you i don't know.
Going through all this praying I can get through my Physics 11C class 🙏
When we say from A to B or B to A do we mean the direction of the electrons or the direction of the current?
Thank you for your efforts.
Thanks man for this work !
Someone explains to me please why sometimes the negative sign for the work formula is skipped, to me it does not make any sense to skip it.
Thank you once again.
Why does a positive charge always accelerates toward the lower electric potential end and a negative charge always accelerate toward the higher electric potential end in an electric field?
Why do I pay tuition for college. 33 minute video and I learned more than I have in 2 hours of lectures.
thanks for doing this !
Broo!! I still convinced that u were sent by God. Thank you soo much man
Please teach about self inductance
Thank you so much
You’re the best.
Thanks it was help full
Why did you delete your previous electric field videos from 4 years ago? I really need those
