To minimize transformer core losses while maintaining high flux density, the core can be made of
A) copper
B) silver
C) laminated steel
D) mica

Question

Quizplus · Accepted Answer

Laminated steel is used in transformer cores to minimize eddy current losses while maintaining high flux density. The lamination reduces the path for eddy currents, thus reducing losses and heat generation without affecting the magnetic properties. Copper and silver are conductive materials used for winding, not for reducing core losses, and mica is an insulating material.
