Definition of Electric Potential:
Electric potential is a location dependent quantity that expresses the amount of potential energy per unit of charge at a specified location. Mathematically, electric potential is the quantity of electric potential energy per unit of charge. Typical units on electric potential are Joules per Coulomb (abbreviated J/C). The term voltage is sometimes used in place of the phrase electric potential. Because of the use of the term voltage, the units of electric potential is the Volt. One volt is equivalent to a J/C.
