An AC circuit has R= 100 Omega , C= 2 mu and L= 80 mH, connected in series. The quality factor of the circuit is :

Answer the following: (a) What do you understand by 'sharpness of resonance' for a series LCR resonant circuit? How is it related with the quality factor 'Q' of the circuit? Using the graphs given in the diagram, explain the factors which affect it. For which graph is the resistance (R ) minimum? (b) A 2 muF capacitor, 100 Omega resistor and 8 H inductor are connected in series with an ac source. Find the frequency of the ac source for which the current drawn in the circuit is maximum. If the peak value of emf of the source is 200 V, calculate the (i) maximum current, and (ii) inductive and capacitive reactance of the circuit at resonance.
