Reactive power (Pr)in a capacitor is defined as the rate atW hich a capacitor stores or returns energy and is measured in:
A)watts reactive.
B)volt-ampere reactive.
C)current per time constant.
D)volts per time constant.

Question

Quizplus · Accepted Answer

Reactive power in a capacitor is measured in volt-ampere reactive (VAR). This is because reactive power represents the exchange of energy between the source and load without actually doing any work. It is not measured in watts, which only represents real power that is converted into useful work. It is also not measured in current per time constant or volts per time constant, as these units are specific to capacitor charging and discharging dynamics, but do not represent a measure of reactive power.
