volt Scientific  

/ vōlt /

1. The SI derived unit used to measure electric potential at a given point, usually a point in an electric circuit. A voltage difference of one volt drives one ampere of current through a conductor that has a resistance of one ohm. One joule of work is required to move an electric charge of one coulomb across a potential difference of one volt. One volt is equivalent to one joule per coulomb.

2. See also Ohm's law

volt Cultural  

1. The unit of electromotive force, the volt measures how much “pressure” there is in an electric circuit. The higher the voltage, the more electrical current (see also current) will flow in the circuit.
