MHT CET · Physics · Alternating Current
In LCR series circuit, \(\mathrm{R}=18 \Omega\) 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
- A 400 W
- B 600 W
- C 800 W
- D 900 W
Answer & Solution
Correct Answer
(C) 800 W
Step-by-step Solution
Detailed explanation
\(P = \frac{V_{rms}^2 R}{Z^2}\) \(P = \frac{(220 \, V)^2 \times 18 \, \Omega}{(33 \, \Omega)^2}\)
