Expert Solution

Step 1

To solve above problem, one should have basic idea about working of AC circuits.

In ac circuits having energy storage elements like L and C their impedance is a function of supply frequency.

Ac circuits cannot be solved directly by applying rules of arithmetic. To solve AC circuit we have to solve them in phasor domain where, reactive components are added together and resistive components together and to add the both phasor sum is required.

Active power is only consumed by resistive loads and reactive power in the circuit comes from inductor and capacitor connected in the circuit.

If reactive power is zero means either the circuit is in resonance no inductors and capacitors present in the circuit.
