What type of power is characteristic of AC electrical circuits with reactive components?

The term that accurately describes the characteristics of AC electrical circuits with reactive components is "reactive power." In AC circuits, particularly where inductors or capacitors are involved, reactive power plays a key role in determining how voltage and current interact.

Reactive power is defined as the power that oscillates between the source and the reactive components in the circuit, such as inductors and capacitors. It does not perform any useful work, but rather, it is essential for maintaining the voltage levels necessary for active power (the power that does actual work) to be delivered to the load. Reactance, which is the resistance from inductors and capacitors to the flow of current, contributes to this unique scenario of power in alternating current systems.

In contrast to reactive power, apparent power represents the combination of real power and reactive power in an AC system, measured in volt-amperes (VA). While it encompasses the total power flow, it does not specifically reflect the work done by or the reactive characteristics within the circuit.

Real power, on the other hand, is the actual power consumed by the circuit for useful work, measured in watts (W). Demand power refers to the maximum amount of power required by a system at any given time and is
