The difference arises because of reactive power, which doesn’t perform useful work but is necessary for maintaining voltage levels in AC systems. For instance, a generator rated at 100 kVA with a power factor of 0.9 can only deliver 90 kW of real power. This distinction is vital for sizing generators, transformers, and other equipment to ensure they can handle the load without overheating or failing.
