An inductor of re A. 8 W.
B. 12 W.
C. 14.4 W.
D. 18 W.
The average power dissipated by resistor (power is NEVER dissipated by inductor or capacitor) of resistance R in any ac circuit with rms current Irms is given by:
where Vrms is the rms voltage and Z is impedance given by:
We can now calculate the power dissipated:
Hence, the correct answer is (c). No other option matches the calculated value.
