Step Down Transformer

A step down transformer has more turns of wire on the primary coil and less turns of wire on the secondary coil. This makes a smaller induced voltage in the secondary coil. Compare this with a step up transformer.

It is called a step down transformer because the output voltage is smaller than the input voltage. If the secondary coil has half as many turns of wire then the output voltagewill be half the input voltage.

Decreasing the voltage does not decrease the power. As the voltage goes down, the current goes up
