Sorry for the primitive diagram. This is a complete circuit oftwo parallel loops with an AC power source in the middle (O).
The "_MMM_"s are resistors. The top _MMM_ is R1 = 203 ohms,bottom _MMM_ is R2 = 184 ohms
The _ÏÏÏ_ is an inductor of 3.38 mH.
The ____| |____ is a capacitor of C = 181 μF
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?
