High Quality Content by WIKIPEDIA articles! In classical electromagnetism, the electric potential (a scalar quantity denoted by ?, ?E or V and also called the electric field potential or the electrostatic 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 there (measured in coulombs). The electric potential at a specific location in the electric field is independent of qt. That is to say, it is a characteristic only of the electric field that is present. The electric potential can be calculated at a point in either a static (time-invariant) electric field or in a dynamic (varying with time) electric field at a specific time, and has the units of joules per coulomb, or volts.
