Question

A transformer is employed to ___________.

• A. convert A.C. into A.C.
• B. convert D.C. into A.C.
• C. obtain a suitable A.C. voltage
• D. None

Answer 1

The correct option is C obtain a suitable A.C. voltage

Answer is C.
Transformers are capable of either increasing or decreasing the voltage and current levels of their supply, without modifying its frequency, or the amount of Electrical Power being transferred from one winding to another via the magnetic circuit. So the current is sent through step up transformers to increase the voltage and to push the power over long distances.
Hence, transformer is employed to obtain a suitable A.C. voltage.
