Which Among the Following, is Not a Cause for Power Loss in a Transformer- Bzziii

Which among the following, is not a cause for power loss in a transformer- 

(i) Eddy currents are produced in the soft iron core of a transformer. 

(ii) Electric Flux sharing is not properly done in primary and secondary coils.

(iii) Humming sound produed in the tranformers due to magnetostriction. 

(iv) Primary coil is made up of a very thick copper wire.

(iv) Primary coil is made up of a very thick copper wire.

Explanation:

Primary coil is made up of a very thick copper wire, is not a cause for power loss in a transformer.Primary coil made of Thick Coper wire has very less R. Therefore negligible power loss.
