Analyse a series RLC circuit for resonance, bandwidth and damping.
At resonance the reactances cancel and impedance drops to the resistance alone. The Q factor sets how sharp that resonance is, and bandwidth is the resonant frequency divided by Q. High Q gives narrow selectivity — good for tuning, bad for transient response, since a high-Q circuit rings for many cycles after a disturbance.
