# volt-amperes reactive

## Definitions

### Electronics

- The
__power__ in an __AC circuit__ which cannot perform work. It is calculated by the following formula: *P* = *I*·V·sinθ, where *P* is the power in watts, *I* is the current in amperes, *V* is the voltage in volts, and sinθ is the __sine__ of the __angular phase difference__ between the current and the voltage. Its abbreviation is VAR. Also called reactive __volt__-amperes, reactive power, idle power, wattless power, or quadrature power. - acronymVAR
