Show that , if a driven oscillator is only lightly damped and driven near resonance, the Q of the system is:

Q = 2*Pi {(Total Energy)/(Energy loss during one period)}

where Q = Wr/2B Wr = resonance (angular frequency)

B = damping parameter

Solution Summary

This solution calculates the energy lost over one period using the resonance (angular frequency) and damping parameter to then find the Q of the system. All steps are shown with a brief explanation.
