Volt

Unit of potential difference or electromotive force. One

volt is the potential difference needed to produce one

ampere of current through a resistance of one ohm.

Volt-Amperes (VA)

The current flowing in a circuit multiplied by the voltage

of that circuit. An expression of the output rating of a

Watt

Unit of electrical power required to do work at the rate of

one joule per second. One watt of power is expended

when one ampere of direct current flows through a

resistance of one ohm. In an AC circuit, true power is the

product of effective volts and effective amperes,

multiplied by the power factor. One horsepower is equal

to 746 watts.
