Power, Power Factor & Wattless Current

In series LCR circuit R $= 18\ \Omega$ and impedance is $30\ \Omega$ . An rms voltage 210 V is applied across the circuit. The true power consumed in AC circuit is nearly

Show answer and solution

Answer: (c)

True power $P = \frac{V^2R}{Z^2}$
$P = \frac{210^2\times18}{30^2} = \frac{44100\times18}{900}$
$P = 882\text{ W}$
So the answer is (c) 882 W.
