The ratio of power factor of purely resistive circuit to purely reactive circuit is ( 0^ = 1 and 90^ = 0 )

Step-by-step solution

The power factor of an AC circuit is given by , where is the phase difference between the voltage and the current. For a purely resistive circuit, the voltage and current are in the same phase, so = 0^ . Power factor = 0^ = 1 For a purely reactive circuit (purely inductive or purely capacitive), the phase difference between voltage and current is = 90^ . Power factor = 90^ = 0 The ratio of the power factor of a purely resistive circuit to a purely reactive circuit is: Ratio = 1 0 = Thus, the ratio is infinite. Answ
