A capacitor and coil or LC circuit in parallel resonant circuit is called a tuned or tank circuit.

They are used in the tuner circuit to generate signals of a particular frequency or picking up signals of a particular frequency.

At Resonance:

\(X_L=X_C\)

\(2\pi fL={1\over 2\pi fC}\)

\(f={1\over 2\pi \sqrt{LC}}\)

where, f = Frequency

L = Inductance

C = Capacitance

The frequency is inversely proportional to L and C.
