2PRACTICE PROBLEM
A homeowner has a series RLC circuit in her home's electrical system. The circuit includes an 80 Ω resistor, a 0.15 H inductor found in a ceiling fan, and a 45 μF capacitor incorporated into the lighting system. The home's electrical supply provides 240 V at a frequency of 50 Hz. Determine the phase angle ϕ.
