Question

If a transformer has 100 turns on the input side and 10 turns on the output side, and you put 120 volts in, how many volts come out?

Accepted Answer

You will get 12 volts out. A transformer changes the voltage—which is the electrical pressure moving power through a wire—using two coils of wire wrapped around a core. The number of loops, or turns, on each side determines the change in voltage. In your case, the input side has 100 turns and the output side has 10 turns. Because 10 is one-tenth of 100, the output voltage will be one-tenth of the input voltage. Think of it like a gear system on a bike where changing the size of the gears changes how much force you need to pedal; here, the ratio of the turns acts as the gear that drops the 120 volts down to 12 volts.
