Problem
(a) Define the term bandwidth for the current–frequency response of a series RLC circuit.
(b) What is meant by the sharpness of resonance with reference to this response?
(c) Draw a qualitative graph of the current amplitude Im versus driving frequency f for a series RLC circuit. Clearly mark on the sketch:
(i) the resonant frequency f0, and
(ii) the frequencies that bound the bandwidth.
