How the unit of reactive power is written? - Quora

In a simple alternating current (AC) circuit consisting of a source and a linear time-invariant load, both the current and voltage are sinusoidal at the same frequency. If the load is purely resistive, the two quantities reverse their polarity at the same time. At every instant the product of voltage and current is positive or zero, the result being that the direction of energy flow does not reverse. In th… WebFeb 1, 2012 · It can be expressed in complex form as apparent power (KVA)=active power (KW) + i reactive power ACTIVE POWER (KW): The unit of active or real power in an ac circuit is KW.
