A » Power factor in a circuit can be measured using a power factor meter or a multimeter with power factor capabilities. It is the ratio of real power, measured in watts, to apparent power, measured in volt-amperes. For precise measurement, connect the meter to the circuit, ensuring it reads both voltage and current. Accurate readings help optimize energy efficiency and reduce electrical costs.

A »Power factor is measured using a power factor meter or calculated by dividing the real power (kW) by the apparent power (kVA). It's the ratio of true power to apparent power in an AC circuit, indicating efficiency. A higher power factor (closer to 1) indicates more efficient use of electrical power.
