Is it possible to introduce local charge on a conductor?
The Attempt at a Solution
I know that electrons can move freely from atom to atom in the conductor, so if you introduce excess electrons to the conductor, they'll spread out and there won't be a local charge. But, in this situation, would there be a local charge that only lasts for a moment, before all the electrons are able to spread out across the conductor, moving from atom to atom?
Also, if you transferred some electrons from the conductor to another object, would it have a locally positive charge in the area where electrons were lost or would those protons spread out as well, moving from atom to atom? I think this would happen because I think only electrons can move freely in conductors, not protons, but I'm not sure.
Also, could the protons and electrons in a conductor repel each other so that they separate and one side of the conductor would be positive while the other side would be negative?
