Transformer is used in rectification to _ the supply voltage.
Correct answer: B. Step down
- A. Step up
- B. Step down
- C. Equalize
- D. None of these options is correct
Explanation

About Transformers
Transformers transfer alternating electrical energy between coils by mutual induction, with voltage ratio determined by the turns ratio. The topic covers step-up and step-down transformers, current changes, ideal power conservation and practical losses such as heating and flux leakage. A transformer requires changing magnetic flux, so it does not operate with steady direct current.
