Power factor The term 'Power factor' as it applies to the area of reclamation can be defined as ' The ratio of real to total power. In alternating-current power transmission and distribution, the cosine of the phase angle between the voltage and current. When the load is inductive such as an induction motor, the current lags the applied voltage, and the power factor is said to be a lagging power factor. When the load is capacitive such as a synchronous motor or a capacitive network, the current leads the applied voltage, and the power factor is said to be a leading power factor. The ratio of the true power passing through an electric circuit to the product of the voltage and amperage in the circuit. This is a measure of the lag or load of the current with respect to the voltage'.
