The core of a transformer is laminated because (a) ratio of voltage in primary and secondary may be increased (b) energy losses due to eddy currents may be minimised (c) the weight of the transformer may be reduced (d) rusting of the core may be prevented.

Answer: (b). Laminations are thin sheets insulated from each other. They block the large eddy current loops in the core, so heat loss is minimised. So the answer is (b) energy losses due to eddy currents may be minimised.

The core of a transformer is laminated because

Show answer and solution

Answer: (b)

Laminations are thin sheets insulated from each other.
They block the large eddy current loops in the core, so heat loss is minimised.
So the answer is (b) energy losses due to eddy currents may be minimised.
