Question

In a step-up transformer, the number of turns in the primary are .................. than the number turns in the secondary.

• A. more
• B. less
• C. same as
• D. None of the above

Answer 1

Answer: (B)

less

If the secondary voltage is less than the primary voltage, the transformer is known as a STEP-DOWN transformer. If the secondary voltage is greater than the primary voltage it is known as a STEP-UP transformer.

Hence, in a step-up transformer, the number of turns in the primary is less than the number turns in the secondary.
