A particular inductor has appreciable resistance. When the inductor is connected to a 12 V battery, the current through the inductor is 3.0 A. When it is connected to an ac source with an rms output of 12 V and a frequency of 60.0 Hz, the current drops to 2.0 A.
a) Find the impedance of the circuit at 60.0 Hz. (don't forget about the resistance of the circuit.)
b) Find the inductance of the inductor.
