Physics Alternating Current MHT CET 2026

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

(A)360 W
(B)420 W
(C)490 WCorrect
(D)600 W

Answer: (C)

Solution

The rms current is A. True (average) power is dissipated only in the resistance: W, option (C). Equivalently V_{rms}I_{rms}$φ =
