1.	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.
Answer» Answer is (iv) Primary coil is made up of a very thick copper wire. as Primary coil made of Thick Coper wire has very less R. Therefore negligible power loss. Rest all options are reasons for power losses in a transformer.
