Power, Power Factor & Wattless Current

In LCR series circuit, R = 18 $\Omega$ and impedance $33\ \Omega$ . An r.m.s. voltage of 220 V is applied across the circuit. The true power consumed in a.c. circuit is

Show answer and solution

Answer: (c)

True power $P = \frac{V^2R}{Z^2}$
$P = \frac{220^2\times18}{33^2} = \frac{48400\times18}{1089}$
$P = 800\text{ W}$
So the answer is (c) 800 W.
