What is the power factor and how does it affect electric power?

Question

Accepted Answer

Power factor is a measure of how effectively electrical power is being used and it affects the efficiency of electrical systems.

Power factor is the ratio of real power (kW) to apparent power (kVA) in an electrical system.
It indicates how much of the total power is being used for useful work.
A power factor of 1 means all the power is being used effectively, while a power factor less than 1 indicates inefficiency.
Low power factor can result in increased energy consumption, higher electricity bills, and reduced capacity of electrical systems.
Power factor can be improved by using power factor correction devices or by optimizing the design and operation of electrical systems.
