- A primary coil of a transformer is connected to a 120V source and draws a 12 A. The secondary coil has 800 turns and a current of 4.0 A. What is the voltage in the secondary coil?A 2.2 Henry inductor and a 177Ω resistor are connected in series with a 24V battery. A long time later the battery is removed from the circuit and replaced with a conducting wire so the inductor is in series with the resistor.
