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

$400 W$
$800 W$
$600 W$
$200 W$

Solution: The correct answer is A $400 W$

Given : $V_{r m s} = 220$ V, $R = 18 Ω$ and $Z = 33 Ω$

We get $P = 400 W$
