The value of L,C and R for a circuit are 1H, 9F and `3Omega` . What is the quality factor for the circuit at resonance ?

How can you improve the quality factor of series resonance circuit ?

The power factor is an L - C-R circuit at resonance is

In an L-C-R series, AC circuit at resonance

In series L-C-R circuit the quality factor is

In series L-C-R circuit the quality factor is

In a series LCCR circuit having L=30 mH, R=8 Omega and the resonant frequency is 50 Hz. The quality factor of the circuit is

A 100 V, AC source of frequency 500 Hz is connected to an LCR circuit with L = 8.1 mH , C = 12.5 mu F, R = 10 Omega all connected in series as shown in the figure. What is the quality factor of the circuit?
