Power factor is the ratio of real power to apparent power in an AC circuit.

• Power factor is a measure of how efficiently electrical power is being used.

• It ranges from 0 to 1, with 1 being the most efficient.

• A low power factor can result in higher energy costs and equipment damage.

• Capacitors can be used to improve power factor.

• Power factor is important in industries where large amounts of electrical power are used.
