Obtain the resonant frequency and Q-factor of a series LCR circuit with L = 3.0 H, C = 27 µF, and R = 7.4 Ω. It is desired to improve the sharpness of the resonance of the circuit by reducing its ‘full width at half maximum’ by a factor of 2. Suggest a suitable way.

The resonant frequency of the source in the LCR series circuit is

We should reduce the resistance to half to improve the sharpness of the circuit’s resonance by reducing its ‘full breadth at half maximum’ by a factor of two.
