A transformer with more turns in the secondary than in the primary is a:
- astep-down transformer
- bstep-up transformer
- cd.c. transformer
- drectifier
Original Khojo Papers practice question — not from a past board paper.
Answer
step-up transformer
No citable source has been recorded for this record. Treat it as practice material, not as fact.
Explanation
The voltage ratio equals the turns ratio, so more secondary turns give a higher secondary voltage.
