Intro to electric potential | Electric potential and capacitance | Physics | Khan Academy

The electric potential at a point in space indicates how much potential energy a coulomb of charge would have at that point. Its units are joules per coulomb, also called volts.

Khan Academy is a nonprofit organization with the mission of providing a free, world-class education for anyone, anywhere. We offer quizzes, questions, instructional videos, and articles on a range of academic subjects, including math, biology, chemistry, physics, history, economics, finance, grammar, preschool learning, and more. We provide teachers with tools and data so they can help their students develop the skills, habits, and mindsets for success in school and beyond. Khan Academy has been translated into dozens of languages, and 15 million people around the globe learn on Khan Academy every month. As a 501(c)(3) nonprofit organization, we would love your help!

I feel lucky and bad in the mean time that im getting this much of quality educational content for free. You deserve respect And my tuition too tbf

[TheMeezanUrdu]

This is amazing! You are saving the students hours every five minutes they spend on watching your amazing lectures! Love from Pakistan!

Floatheadphysics 😮
The only man on this entire internet and literally on earth who makes anyone love physics.

He explains the concepts as if he is teaching to an beginner


Thanks mahesh

[nikhilbhatt]

the way of your learning is really awesome.you are god of concept clearing.

[oliverrainer]

This cleared things up a ton. Thanks for the help

[AbinayaPalanikumar-cf]

Really I like ur videos
This helped me a lot to solve questions 😊

[RickRudy]

This man saved me from drowning. Thank you so much sir. You're a great teacher!

After 14 years of study i didn't get it. But now it's crystal clear to me what is potential energy. Thanks a lot for the resources I am grateful to khan academy & Mahesh sir

[Jaiyaxhkateacher]

This guy clear my doubts as transparent glass

[VG__]

1:10, 2:07 yeah
2:25 potentials are just indicators
4:30
5:48 potential and potential energy
7:35 gist

[shreya]

Glad that I know about this channel:-)

[NavneetKaur-deji]

Very well explained 👏.. Keep it up sir!

Using his gravitational analogy one could have been more succinct.
If Mgh represents gravitational potential energy (PE), Voltage is analogous to the "gh" bit or gravitational acceleration x height in the direction of acceleration. In electricity gravitational acceleration is represented by electric field E (which also is acceleration) and height by d (displacement) along the E direction. Just as multiplying gh by mass = Mgh (gravitational potential energy) so multiplying Ed by Q = QEd = electrical potential energy. The "Ed" bit is also called Voltage or EMF. Thats it in a paragraph
Recapping, the "gh" bit is analogous to Ed or Voltage or EMF or "POTENTIAL". Multiplying by Q gives Electrical Potential Energy = QEd = QV

I know this is out of context but I LAAV YOUW!! thanks for simplifying complex stuff so much that even a kid wouldnt have any hard time understanding it

[biplobhimu]

That's what I was searching for ❤

[im_sorx]

this saved me brother, thank you sm❤️😔

[TheRoonster]

Great! What application is used for writing on blackboard?

[iasali]

One day you will receive noble prize my wish with you

[ProToColGm]

does that mean my fat friend sitting next to me is more energetic than me, as Potential Energy depends on mass?😂

[untecky]

Why electric potential of positive terminal is greater than negative terminal
