A FM radio receiver has a series LCR circuit with L = 1 `muH`, and R = 100 `Omega`. The antenna receives radio waves and induces a sinusoidally alternating emf of ampli- tude 10 `muV`. The induced voltage is fed to the series LCR circuit. The capacitance in the circuit is adjusted to a value of C = 2 pF.
(a) Find the frequency of radio wave to which the radio will tune to.
(b) Find the rms current in the circuit.
(c) Find quality factor of the resonance.
