Power factor is a measure of how effectively electrical power is being used in a circuit.
Power factor is the ratio of real power to apparent power in a circuit.
It is a number between 0 and 1, with 1 representing perfect efficiency.
A low power factor indicates inefficient use of electrical power.
Power factor can be improved by using power factor correction devices.
For example, inductive loads like motors have a lower po
