Resonance, Bandwidth & Q Factor

A series LCR circuit containing a resistance ' R ' has angular frequency ' $\omega$ '. At resonance the voltage across resistance and inductor are ' $V_R$ ' and ' $V_L$ ' respectively, then value of inductance ' $L$ ' will be

Show answer and solution

Answer: (d)

$I = \frac{V_R}{R}$ and $V_L = I\omega L$ .
$L = \frac{V_L}{I\omega} = \frac{V_L R}{V_R\omega}$
So the answer is (d) $\frac{V_L R}{V_R\omega}$ .
