Question

A series circuit contains a 3.00 H inductor, a 3.00 mu F capacitor, and a 25.0 Ohm resistor connected to a 120 V (rms) source of variable frequency. Find the power delivered to the circuit when the frequency of the source is each of the following: the resonance frequency one-half the resonance frequency one-fourth the resonance frequency two times the resonance frequency four times the resonance frequency From your calculations, can you draw a conclusion about the frequency at which the maximum power is delivered to the circuit?
