A particular inductor has appreciable resistance. When the inductoris connected to a 11.5 V battery, the current in the inductor is4.54 A. When it is connected to AC source with an rms output of11.5 V and a frequency of 69 Hz, the current drops to 1.94 A.
Find the impedance at 69 Hz. Answer in units of Ω .
Find the inductance of the inductor. Answer in units of mH.
