In electrostatic equilibrium, where does excess charge given to an isolated conductor reside?
Answer and explanation
Correct answer: On the outer surface of the conductor
In electrostatic equilibrium, the electric field within the conducting material is zero. If excess charge remained in the interior volume, it would produce an internal electric field and charges would continue to move until equilibrium was reached. Therefore, excess charge resides on the outer surface, not throughout the volume or at the centre.
