Correct option is (b) Volt Amperes Reactive (VAR) The best I can explain: Reactive power is expressed in Volt Amperes Reactive (VAR) and power is expressed in watts and apparent power is expressed in Volt Ampere (VA). 0 votes. WebJan 26, 2024 · Reactive power is the resultant power in watts of an AC circuit when the current waveform is out of phase with the waveform of the voltage, usually by 90 degrees if the load is purely reactive, and is the result of either capacitive or inductive loads. Only when current is in phase with voltage is there actual work done, such as in resistive ...
