MHT CET 2024 3rd May Evening Shift | Alternating Current Question 42 | Physics

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

$\frac{V_R R}{V_L \omega}$

$\frac{V_L}{V_R R \omega}$

$\frac{V_R \omega}{V_L R}$

$\frac{\mathrm{V}_{\mathrm{L}} \mathrm{R}}{\mathrm{V}_{\mathrm{R}} \omega}$
