A signal source of fixed amplitude is connected successively to two series LCR circuits, A and B. Circuit A:

L=0.50\,\text{H},\;C=20\,\mu\text{F},\;R=10\,\Omega

Circuit B:

L=0.50\,\text{H},\;C=20\,\mu\text{F},\;R=25\,\Omega

Answer the following: (a) Calculate the quality factor for each circuit at resonance. (b) Determine the bandwidth (in rad s

^{-1}

) for each circuit. (c) Which circuit produces the sharper resonance curve? Explain how your numerical results support your answer.
