## Scientific definitions for volt

volt

[ 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. See also Ohm's law.

## Cultural definitions for volt

volt

[ (vohlt) ]

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.

## Notes for volt

Ordinary household outlets are usually rated at 115 volts, car batteries at 12 volts, and flashlight batteries at 1.5 volts.
