Reactive power expressed in which unit?

Explanation:
Reactive power is the portion of electrical power that is alternately stored and released by inductive and capacitive elements, causing a phase difference between voltage and current. It represents energy that does not perform real work but supports the alternating magnetic and electric fields in the system. Because this exchange is quantified as VAR, the correct unit is volt-amps reactive. In contrast, voltage is measured in volts, real power (the work actually done) is in watts, and current is in amperes. The overall apparent power, which combines real and reactive components, is measured in volt-amps (VA).
