Apparent Power is primarily measured in which of the following units?

Apparent Power is primarily measured in Volt-Amperes (VA), which is a unit that combines both real power and reactive power in an AC (Alternating Current) circuit. While Watts are used to measure real power, which represents the actual power consumed by the load, Volt-Amperes represent the total power that flows in the circuit, taking into account both the power that does useful work and the power that oscillates back and forth in the system but does no net work.

In AC circuits, apparent power can be calculated by multiplying the RMS (Root Mean Square) values of voltage and current, leading to the understanding that it is a measurement of the total potential power. This distinction is crucial when analyzing electrical systems, as it helps engineers and technicians understand both the effective power used and the total power present in the system, which can have implications for equipment sizing and efficiency.

The other units provided—Watts, Ohms, and Coulombs—measure different electrical concepts. While Watts measure real power, Ohms measure resistance, and Coulombs measure electric charge, they are not applicable for representing apparent power. Thus, understanding that Volt-Amperes encapsulate both aspects of power in alternating current systems clarifies why this unit is the correct
