Description : How do you measure power factor?

Answer : P= 1.83*V*I*COS@ where P is power V is voltage I is current COS @ is P.F COS@= P/(1.83*V*I) in other way cos @ = true power/apparent power

Description : What is the use of power factor correction?

Description : Can you have a power factor greater than 1?

Answer : We cannot have power factor greater than 1. As it is a measure of cosine of angle between voltage and current.
