A) to increase the electric field
B) to increase the magnetic field
C) (c) to reduce the loss of energy due to eddy currents
D) to decrease the resistance
Correct Answer: C
Solution :
The core used in transformer and other electro-magnetic instruments is laminated, so that the resistance is increased. Due to this increase, energy loss due to eddy current is reduced.You need to login to perform this action.
