Answer #1

The resonance frequency is a property of the circuit, irrespective of whether there is any signal going through the circuit. A passive circuit cannot change the frequency of the input signal, but it can change its amplitude. The frequency in the passive circuit will always be the input frequency, the resonance frequency is irrelevant.

The resonant angular frequency in an LC circuit equals the square root of the inverse of capacitance (C measured in farads), times the inductance of the circuit (L in henrys).[5]

LC

Resonance frequency, f = ? / 2? = (LC)-
