Q:

To what is a joule per coloumb equivalent?

A:

Quick Answer

Electrical potential, the amount of electric potential energy per unit charge, is measured in joules per coulomb or volts. The two can be used interchangeably, one joule per coulomb is equivalent to one volt.

Full Answer

Electrical potential energy can be increased through the work done as like charges are brought together. As two like charges repel away from each other, electrical potential energy is reduced as it is transferred to kinetic energy. The change in electrical potential energy in a process is measured in joules. The amount of electrical potential energy, or work done, is dependent on the amount of charge unit moved and is measured in coulombs. The electrical potential energy, or voltage, can be determined by dividing the electrical potential energy by the charge units. The unit for voltage is therefore measured in joules per coulomb, more commonly referred to as volts.
