Question

What is the relation between electric potential energy and electric potential

Answer 1

Electric potential energy Ue is the potential energy stored when charges are out of equilibrium (like gravitational potential energy).

Electric potential is the same, but per charge, Ueq. (Useful when comparing different points.)

An electric potential difference between two points is called voltage, V=Ue2/q−Ue1/q.

Answer 2

The relation between electric potential energy and electric potential are:

Electric potential energy - It is the potential energy stored when charges are out of equilibrium like gravitational potential energy.

Electric potential - It is same but per charge U/q useful for comparing different points.
