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.
