Calculate the ratio of real power to apparent power in AC circuits.
AC Power Parameters
Calculation Results
Apparent power must be ≥ real power
Overview
Power Factor (PF) is the ratio of the real power flowing to the load to the apparent power in the circuit. It is a measure of how effectively electrical power is being converted into useful work.

Pro Tips
Real power (P) is measured in Watts (W).
Apparent power (S) is measured in Volt-Amperes (VA).
Reactive power (Q) is measured in Volt-Amperes Reactive (VAR).

Fun Facts
"A power factor of 1.0 (Unity) is ideal, meaning all power is real."
"Inductive loads (motors) cause a lagging power factor."
