What are half-power frequencies in a series RLC resonance circuit? Derive an expression for bandwidth of the circuit.

Discuss various characteristics of a general parallel RLC circuit at resonance. Derive resonance frequency when (a) coil is loss free (b) capacitor is loss free (c) both are loss free. Draw the equivalent circuit when Q of the circuit is high.
