Electrical Potential of a Conducting Sphere (or Shell)

Physics Ninja looks at the derivation of the electrical potential of a conducting sphere. The electrical potential is found for points outside the sphere as well as for points inside the sphere. In Part 1 evaluate the integral for the potential difference. In Part 2 I integrate of the surface charge density.

Thank you so much! This video was really helpful 🎉

Hey i asked a doubt on cart collision with a spring in a video you posted a year ago. Can you pls ans my question as to why do we not take momentum of spring in those numericals while we are taking momentum of carts

Hey! I have a very silly doubt… what’s the difference between electric potential and electric potential difference?

There's something that is driving me nuts and can't find the answer of anywhere. Since delta V is the line integral of E dot dr from infinity to r, and we are moving against the electric field going from infinity to r (assuming a positive charge), E dot dr should be -kqdr/r^2, not kqdr/r^2, which leaves an extra minus sign which would make V negative at the end. I know it's not supposed to be, but I can't figure out the solution of this issue and I looked everywhere

but if its shell there is no potential in inside why you said sphere or shell on title?

Wow you made this more complicated than it needed to be.
