Power, Power Factor & Wattless Current

In series LCR circuit $R = 10\ \Omega$ and impedance is $30\ \Omega$ . An r.m.s. voltage $210$ V, is applied across the circuit. The true power consumed in AC circuit is

Show answer and solution

Answer: (c)

$I_{rms} = \frac{V}{Z} = \frac{210}{30} = 7\text{ A}$ .
True power $P = I_{rms}^2R = 49 \times 10 = 490\text{ W}$ .
So the answer is (c) 490 W.
