B Correct answer
Explanation

In classical electromagnetism, the electric potential at a point within a defined space is equal to the electric potential energy (measured in joules) at that location divided by the charge (measured in coulombs). The concept of electric potential is used to express the affect of an electric field of a source in terms of the location within the electric field.
