[vohlt] /voʊlt/
noun, Electricity.
the standard unit of potential difference and electromotive force in the International System of Units (SI), formally defined to be the difference of electric potential between two points of a conductor carrying a constant current of one ampere, when the power dissipated between these points is equal to one watt.
Abbreviation: V.
Origin of volt1
First recorded in 1870-75; named after A. Volta


[vohlt] /voʊlt/
  1. a circular or turning movement of a horse.

volt in Science
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.

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 will flow in the circuit.

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