Please find below the solution to the asked query:
- In the case of purely inductive ac circuit, the current will be out of phase by 90 degrees to the voltage
- The expression for power, P = V I cos Φ
- By substituting Φ = 90 degrees in the equation of P, we get P = 0
- Hence, it can be concluded that pure inductor doesn't consume electric power.
