An inductor of inductance L and resistor of resistance R are joined in series and connected by a source of frequency ω. Power dissipated in the circuit is

View answer and explanation

Correct option: B

\frac{{{V^2}R}}{{\left( {{R^2} + {\omega ^2}{L^2}} \right)}}

Option B (

\frac{{{V^2}R}}{{\left( {{R^2} + {\omega ^2}{L^2}} \right)}}

) is correct because it represents the power dissipated in an RL circuit connected to an AC source.
