An inductor of re A. 8 W.

B. 12 W.

C. 14.4 W.

D. 18 W.

Given,
Inductive reactance,
Capacitive reactance,
Resistance,
Rms voltage,

The average power dissipated by resistor (power is NEVER dissipated by inductor or capacitor) of resistance R in any ac circuit with rms current I_rms is given by:

Now,

where V_rms is the rms voltage and Z is impedance given by:

Reactance,

Now,

We can now calculate the power dissipated:

Hence, the correct answer is (c). No other option matches the calculated value.
