Power in AC Circuits
10PRACTICE PROBLEM
A student connects a 100.0 Ω resistor, an inductor L, and a capacitor C, in series across an ac generator of Vrms = 45.0 V. The generator is operating at 150.0 Hz. The circuit's impedance at 150.0 Hz is 125.0 Ω. Calculate the average power transferred to the circuit.
