In a step up transformer, which one of the following statements is correct?

A Number of turns in the secondary coil is less than in primary coil
B Voltage in secondary coil is less than in primary coil
C Current in the primary coil is more than current in the secondary coil
D Current in the primary coil is equal to current in the secondary coil

Verified Solution

Answer & Solution

Correct Answer

(C) Current in the primary coil is more than current in the secondary coil

Step-by-step Solution

Detailed explanation

In a step-up transformer, the current in the secondary is less than the current in the primary.

Apply the relevant identity from the chapter and substitute the values established in the previous step, keeping the original constraint in view.

Use the simplified expression to isolate the unknown, then plug the result back into the question setup to confirm the working is internally consistent.

Cross-check against a boundary or limiting case. Both the dimensional balance and the qualitative behaviour at the extreme should agree with the candidate answer.

Combine the steps above to identify the correct option. The remaining choices each fail at least one of the consistency, dimensional, or boundary checks.
