NEET 2018 Physics RLC Circuits MCQ Question

Type: MCQ-numerical-Medium-Class 12

An inductor 20 mH, a capacitor 100 μF and a resistor 50 Ω are connected in series across a source of emf, V=10sin314tV = 10 \sin 314\, t. The power loss in the circuit is

A

0.79 W

B

0.43 W

C

2.74 W

D

1.13 W

Correct Answer

Option C

Detailed Explanation

The power loss in an RLC circuit is given by P=I2RP = I^2 R, where II is the current. The impedance of the circuit determines the current, which can be calculated using the given values.
