Quizplus · Accepted Answer

Reactive power in an inductor is measured in volt-ampere reactive (VAR). This is because an inductor stores energy in the magnetic field around it and then releases this energy back into the circuit, which affects the voltage and current in the circuit. The measurement of this energy storage and release is given in VAR.
