Which devices changes low voltage alternating current to high voltage

• GP Magnetism

Which one of the following devices changes low voltage alternating current to high voltage alternating current and vice versa?

1. Generator
2. Motor
3. Transformer
4. Vibrator

Answer

A transformer is an electrical device that transfers electrical energy between two or more circuits through electromagnetic induction. A varying current in one coil of the transformer produces a varying magnetic field, which in turn induces a voltage in a second coil.

The correct option is C.
