Answer 2

The correct answer is option (b) 510 W.

Explanation:

• A 220v 50HZ transformer with 0.35 mm thickness laminations has eddy current loss of 120 watt which is two third of the total loss at no load .
• If this transformer is built with 0.7 thick laminations and is worked from 110v 25 HZ then total no load would be ​510 W.
