WebPower factor is defined as the cosine of the angle between voltage and current in an ac circuit. There is generally a phase difference Ø between voltage and current in an ac circuit. cos Ø is called the power factor of the circuit. If the circuit is inductive, the current lags behind the voltage and power factor is referred to as lagging ... WebPower Factor of an alternating current circuit is the ratio of true power dissipation to the apparent power dissipation in the circuit. Also, c o s ϕ = R Z The value of the power of an …
