A kVA is also called which of the following?

Explanation:
In AC circuits, power comes in three related ideas: apparent power, real power, and reactive power. The product V × I gives power, but not all of it is usable energy at once—some of it is stored and returned due to the phase difference between voltage and current. The quantity that uses V × I without accounting for this phase is apparent power, and its unit is kilovolt-amps (kVA). Real power, the usable portion, is measured in kilowatts (kW) and equals apparent power times the power factor (P = S × PF). Kilowatt-hours (kWh) are energy, not instantaneous power. Megavolt-amps isn’t the standard term used here. So the correct expansion is kilovolt-amps.
