Question

What is mean by electric potential ?

Answer 1

Electric potential is the amount of electric potential energy that a unitary point electric charge would have if located at any point in space, and is equal to the work done by an external agent. 

Answer 2

An electric potential (also called the electric field potential or theelectrostatic potential) is the amount of electric potential energy that a unitary point electric charge would have if located at any point in space, and is equal to the work done by an external agent in carrying a unit of positive charge.
