Electric potential | AP Physics | Khan Academy

From the creator

Electric potential describes the electric potential energy per unit charge at a point in space. The electric potential due to multiple point charges can be determined by the principle of scalar superposition of the electric potential due to each of the point charges. The electric potential difference between two points is the change in electric potential energy per unit charge when a test charge is moved between the two points.
