What is the outcome when dividing real power by apparent power?

When dividing real power by apparent power, the outcome represents the power ratio, also known as the power factor. This ratio is crucial in electrical systems as it indicates how effectively electrical power is being converted into useful work output.

Real power, measured in watts (W), refers to the actual power that performs work in the circuit, while apparent power, measured in volt-amperes (VA), represents the combination of both real power and reactive power in an AC circuit. The power ratio provides insight into the efficiency of the electrical system in converting the apparent power supplied into usable power. A higher power ratio indicates a more efficient system, whereas a lower ratio suggests that a significant portion of the apparent power is not being converted into useful work, often due to reactive components like inductors and capacitors in the circuit.

This understanding is essential for linemen and electrical engineers to enhance system performance and reduce losses.
