In electrical engineering, the power factor of an AC power system is defined as the ratio of the real power absorbed by the load to the apparent power flowing in the circuit.

Power factor is an expression of energy efficiency. It is usually expressed as a percentage—and the lower the percentage, the less efficient power usage is. Power Factor (PF) is the ratio of working …

Apr 19, 2024 · At its core, power factor is a measure of how effectively electrical power is being converted into useful work output in an electrical system. In other words, it indicates the efficiency of …

Apr 13, 2025 · Power Factor (PF) is a fundamental measure of electrical efficiency within alternating current (AC) power systems. It reveals how effectively the electrical power supplied by the utility is …

Power factor is defined as the ratio of real (or active) power to apparent power in an AC circuit. Real power (measured in kW) is the energy actually consumed to perform work such as lighting lamps …

The power factor measures the effectiveness of converting electrical power into meaningful work output. Its values can range from 0 to 1 (or, more accurately, from 0 to 100%).

It represents the ratio of real power flowing to the load to the apparent power in the circuit, helping assess how effectively electrical energy is being converted into useful work.
