Transformer is a device to convert
-
- D.C. to A.C.
- Low voltage D.C. into high voltage D.C.
- Low voltage A.C. into high voltage A.C.
- Mechanical energy into Electrical energy
- D.C. to A.C.
Correct Option: C
A transformer is an electrical device that transfers energy from one circuit to another by magnetic coupling with no moving parts. It converts high voltage AC into low voltage AC and vice-versa. It is based upon the principle of mutual induction. Transformers alone cannot convert AC to DC or DC to AC; besides, they cannot change the voltage or current of DC.
