The core of any transformaer is laminated so as to

Options

A. energy losses due to eddy currents may be minimised
B. the weight of the transfomer may be reduced
C. rusting of the core may be prevented
D. ratio of voltage in primary and secondary may be increased.

Answer

A

Explanation

Eddy currents produced in coil oppose the cause of their origin, therefore due to eddy currents, a great amount of energy is wasted in form of heat energy. If core of transformer is laminated, then their effect can be minimised.
