The derived unit of electromotive force, volt is the electric potential difference between two distinct points on a wire capable of carrying a charge. More specifically, a potential difference that will transmit one unit (joule) of energy to each charge (coulomb) that passes through it. More plainly, voltage can be thought of as the amount of "electric pressure" pushing on electrons.
