How can a conducting sphere have no voltage at the surface, and yet have a surface charge when there's a charge outside of the sphere? Wouldn't the surface charge create voltage at the surface?
HOW to think about surface charge and voltage!?
Homework Statement
I'm just trying to think about something that's confusing the hell outta me. If a charge q+ is near a grounded conducting sphere, where the voltage at the surface is zero, we can use image charges to find the electric field and...
