Answer:
True.
Explanation:
A transformer is used either to increase or decrease the voltage.
It has two separate sets of coils of wire. The coils connected to the input voltage are called primary and the output coils are called secondary.
If number of windings (or coils) of wire in primary are less than the windings in secondary, it is a step up transformer because output voltage will be more than the input voltage. In this case the output voltage given out by the secondary will be more than the primary.
If the primary coils are more than the secondary, it is called a step down transformer. In this case, secondary voltage (output voltage) will be less than the primary.
