An electrical device contains a transformer. Its primary coil has 200 turns, and its secondary coil has 20 turns. If the device is plugged into a 120-volt line, what is the output voltage of the device?
Answered by Steve
well, since the voltage ratio is the same as the ratio of turns, you would have

120 * 20/200
