What is the meaning of real power?

Real power, often referred to as active power, is the measure of actual work done by an electrical system and is expressed in watts (W). It represents the portion of electrical power that performs useful work, such as lighting a bulb or powering a motor. Real power is crucial for the efficient operation of electrical devices, distinguishing it from reactive power, which does not perform any useful work but is necessary for maintaining voltage levels in the system.
