Electric potential at a point in space | Physics | Khan Academy

starting from V = U/q how do i derive the formula V = k_e * (q/r)

What if thers negative charge

It's not magic , just it's clear , and that's what our * educational systems* lack

I have only one word for this video - AMAZING

So if you were to place a second charge right on top of Q, the r would be 0, and V would be infinity?

wow this is a great explanation !

The world's best teacher thanks

So nice thanks sir

Is the charge being negative or positive gonna affect the calculation?

Expound on the relationship of Electric Potential between two points in space and Electric Potential value at one point in space.

amazing explanation

Thanks for this amazing video. Very helpful in explaining this topic! Bravo Khan.

you're just too good man!!!

Thanks a lot sir l've been struggling with this topic that was very effective explanation

You're the best. I love u

This is a deadly most wanted technical clearance ever in physics. I was so confused with potential and potential energy and the work done related to them. Now it is clear. I appreciate it very much.

I came across electric potential defined as the amount of work needed to move a charge q to some distance r against(?) the direction of the electric field; hence, V = Er = (kQ/r2) r = kQ/r

may i ask about the potential energy calculated using qv is relative to what point?

Thank you so much, i've been struggling to understand this concept for 2 days!
