Q. For an $RLC$ circuit driven with voltage of amplitude $v_m$ and frequency $\omega_0 = \frac{1}{\sqrt{LC}}$ the current exhibits resonance. The quality factor, $Q$ is given by :

JEE MainJEE Main 2018Alternating Current

Solution:

Quality factor, $Q=\frac{\omega_{0}}{(2 \Delta \omega)}$
$Q-\frac{\omega_{0} L}{R}$
