(D) The $Q$-factor (Quality factor) of a series $LCR$ circuit is defined as the ratio of the resonant frequency to the bandwidth of the circuit.Mathematically,$Q = \frac{\omega_0}{\Delta\omega} = \frac{\omega_0 L}{R} = \frac{1}{R} \sqrt{\frac{L}{C}}$.It represents the sharpness of the resonance peak.$A$ higher $Q$-factor indicates a sharper resonance and better selectivity of the circuit.It depends on the values of inductance $(L)$,capacitance $(C)$,and resistance $(R)$ of the circuit.
