Power in AC Circuits
8PRACTICE PROBLEM
A series RLC circuit is driven by an AC power source of rms 60 V at a frequency of 120 Hz. The resistor has a resistance of 150 Ω, the inductor has an inductance of 125 mH, and the capacitor has a capacitance of 112 mF. Calculate i) the power provided by the AC source and ii) the rate at which electrical energy is lost in the resistor.
