    B

    Explanation:

    Transformer is a device used to convert low a. c. voltage to high a. c. voltage and vice versa.

    There is two types of transformer, they are:

    1. Step up transformer

    It converts low a. c. voltage into high a. c. voltage.

    2. Step down transformer

    It converts low a. c. voltage to high a. c. voltage.
