Question

A transformer is a device used for converting:

• A. high ac voltage and large ac current to low ac voltage and small ac current
• B. high ac voltage and small ac current to low ac voltage and small ac current
• C. low ac voltage and large ac current to high ac voltage and small ac current
• D. low ac voltage and small ac current to high ac voltage and large ac current

Hint:

Transformers are based on the principle of electromagnetic induction. The voltage ratio between primary and secondary coils is directly proportional to the number of turns in each coil.

Answer 1

The Correct Option is C

A transformer is an electrical device that alters the voltage level in an alternating current (AC) circuit. It operates on the principle of electromagnetic induction and can either step up or step down the voltage.
- A step-up transformer increases voltage and decreases current.
- A step-down transformer decreases voltage and increases current.

In this specific scenario, the transformer converts low AC voltage and high AC current into high AC voltage and low AC current. This operation is characteristic of a step-up transformer, which has fewer turns in its primary coil and more turns in its secondary coil.
