If the secondary coil has more turns than the primary, the transformer is:
AStep-off
BStep-in
CStep-up
DStep-out
Answer & Solution
Correct answer: C. Step-up
1. The turns ratio decides which way the voltage moves.
2. More turns on the secondary means a higher secondary voltage.
3. If the secondary has a greater number of turns, the voltage is stepped up.
4. That arrangement is called a step-up transformer.
