If the coils of a transfomer are made up of thick wire, then

A

eddy currents loss will be more

B

magnetic flux leakage is reduced

C

Joule's heating loss is increased

D

Joule's heating loss is reduced

Text Solution

Verified by Experts

The correct Answer is:
D
When wire is thick, its resistance reduces. Therefore, joule's heating loss is reduced.
