Damping and Resonance
Damping reduces the size of the oscillations at resonance. There is still a maximum amplitude reached but it is much lower than when the system is undamped. We say that damping reduces the sharpness of resonance. This becomes clearer if we look at the graph on the right.
It shows the amplitude of oscillation against frequency for different levels of damping.
