Answer: Generally speaking, for an underdamped RLC system, the quality factor (Q) provides a comparison of the resonant frequency (w0) and the rate of decay or damping factor of the oscillating states (a). Circuit current assumes its maximum value because the impedance is minimum. Q can be defined for networks having two elements. The process of this conversion includes few steps.
