Question

A series circuit contains a 3.00-H inductor, a 3.00-mF capacitor, and a 30.0-V 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

(a) the resonance frequency,

(b) one-half the resonance frequency,

(c) two times the resonance frequency, and

From your calculations, can you draw a conclusion about the frequency at which the maximum power is delivered to the circuit?
