AIPMT PRELIMS 2006 Physics Transformers MCQ Question

Type: MCQ-conceptual-Medium-Class 12

The core of a transformer is laminated because :

A

energy losses due to eddy currents may be minimised

B

the weight of the transformer may be reduced

C

rusting of the core may be prevented

D

ratio of voltage in primary and secondary may be increased

Correct Answer

Option A

Detailed Explanation

Laminating the core of a transformer reduces energy losses due to eddy currents, which are minimized by increasing the resistance of the core.
