To solve the above problem, one should have a basic idea about the working of AC circuits.
The above given circuit is a R-L-C circuit.
In AC circuits having energy storage elements like L and C, the impedance is a function of the supply frequency.
AC circuits cannot be solved directly by applying the rules of arithmetic. An AC circuit should be solved in the phasor domain, where reactive components are added together and resistive components together and then both are summed up to obtain the phasor sum.
Active power is only consumed by resistive loads and reactive power in the circuit comes from the inductor and capacitor connected in the circuit.
If the reactive power is zero, it means either the circuit is in resonance or there are no inductors and capacitors present in the circuit.
