An 80.0-O resistor, a 200-mH inductor, and a 0.150-µF capacitor are connected in parallel across a 120-V (rms) source operating at 374 rad/s.
(a) What is the resonant frequency of the circuit?
(b) Calculate the rms current in the resistor, inductor, and capacitor.
(c) What rms current is delivered by the source?
(d) Is the current leading or lagging behind the voltage? By what angle?
