power factor Quiz Practice Quiz | Power Factor

The ratio of real power to apparent power. — Power factor is defined as real power divided by apparent power (P/S).

Purely resistive load. — A power factor of 1 signifies that the voltage and current are in phase, characteristic of a resistive load.

An inductive load like a motor or inductor. — Inductive loads cause current to lag voltage, leading to a lagging power factor.

By adding capacitive loads. — Adding capacitive loads counteracts inductive loads, improving the power factor.

No units; it's a dimensionless quantity. — Power factor is a ratio, thus it has no units.
