The core of a transformer is laminated to:
- A increase energy loss
- B reduce energy loss
- C increase magnetic flux
- D increase resistance
Answer & Solution
Correct Answer
(B) reduce energy loss
Step-by-step Solution
Detailed explanation
Laminating the core with thin insulated sheets breaks the continuous path for circulating eddy currents. This significantly reduces the heating and energy loss caused by these currents, thereby improving the efficiency of the transformer. B) reduce energy loss.
