Series Resonant Circuit

A resonant circuit in which the source voltage is connected in series with a capacitor and an inductor to furnish a low impedance at the frequency at which the circuit is resonant.

It exhibits minimum impedance at resonance.

The undamped resonant angular frequency is given by:

The quality factor is given by:

Where

U = the stored energy in the systems
P = the mean power in the system

at frequencies close to resonance:
