Here is a java applet that plots the parameters of an RLC circuit. Play with it. See how the sharpness of the resonance peak changes as you increase and decrease the resistance. See how the resonant frequency changes as you change the capcitance and the inductance. Set the frequency to be on resonance, then off resonance, then click on the radio button for i(t), V(t) and see how the appled voltage and the current changes as a function of the frequency.

Here is an applet that illustrates the mechanical alaogue. Try setting the frequency to the resonant frequency, then look at the "elongation diagram". See how the amplitude gets larger with each successive oscillation.
