A transformer is a piece of iron which has a pair of wires coiled around it. Alternating current in the input coil makes the iron an alternating magnet, which generates current in the second coil via electromagnetic induction.

Into a perfect transformer is fed a particular voltage and current, hence a particular power (wattage). Out of the transformer must come the same

1. amperage

2. voltage

3. wattage

4. amperage, voltage, and wattage

5. none of the above
