What is the significance of Q factor in a series LCR resonant circuit?

What is the power factor of an LCR series circuit at resonance?

What is the power factor of an LCR series circuit at resonance?

Obtain the resonant frequency and Q-factor of a series LCR circuit ith L = 3.0 H, C = 27 muF , and R = 7.4 Omega . 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.

Give applications of resonance in series LCR circuit.

Can the voltage drop across the inductor or the capacitor in a seris LCR-circuit be greater than the applied voltage of the a.c. source? Jusitfy your answer.

What can we say about the current in LCR series resonance?

Explain the term resonance for a series LCR-circuit. Calculate the resonant frequancy.
