Demonstrate thatat low damping the quality factor `Q` of a circuit maintaining forced oscillations is approximately equal to `omega_(0)//Delta omega`, where `omega_(0)` is the natural oscillation frequency , `Delta omega` is the width of the resonance curve `I(omega)` at the " height " which is `sqrt(2)` times less than the resonance current amplitude.
