Explanation of Solution

Introduction:

A transformer is used to increase or decrease the voltage of an alternating current.

The number of turns in the primary coil is 20 while the number of turns in the secondary coil is 2 . The secondary coil has fewer turns than the primary coil. This type of transformer decreases voltage and hence named as a step-down transformer.

Conclusion:

The transformer is a step down transformer.
