Chapter , Problem 73(choose chapter or problem)
A certain electrical device draws an rms current of at an average power of when connected to a 120-V-rms, 60-Hz power line. (a) What is the impedance of the device? (b) What series combination of resistance and reactance would have the same impedance as this device? (c) If the current leads the emf, is the reactance inductive or capacitive?
