Apparent power is measured in ___.

Explanation:
In AC circuits, apparent power is the product of RMS voltage and RMS current, and its unit is volt-amperes (VA). This distinguishes it from real power, measured in watts, and reactive power, measured in volt-amperes reactive (VAR). Capacitance (measured in farads) is not a power quantity. So the correct unit for apparent power is volt-amps.
