What is the unit for Real Power?

Real power, also known as active power, measures the actual power consumed by a load to perform useful work in an electrical circuit. It is expressed in watts (W). In alternating current (AC) circuits, real power is the portion of total power that contributes to the actual work done, such as lighting a bulb or powering a motor, and is associated with energy consumption over time.

The significance of real power lies in its role in performing work and its billing for consumed energy, as utility companies charge based on real power usage. Understanding this is crucial in electrical engineering and power systems, where distinguishing real power from other types of power—like reactive power and apparent power—is essential for system analysis and design.
