Circuits and Networks

1. What is the basic difference between the series resonant L–C circuit and the parallel resonant L–C circuit?
2. Can you draw the current (i) versus time (t) plot of the series and parallel resonant circuits?
3. From the current versus time plots of series and parallel resonant circuits, how would you define the Q-factor in the two cases?
4. What would be the nature of the impedance of the series resonant circuit at frequencies below the resonant frequency?
5. What would be the nature of the impedance of the series resonant circuit at frequencies above the resonant frequency?
6. In case of a parallel resonant circuit, what would be the nature of the impedance at frequencies below and above the resonant frequency?
7. Can you draw the ...
