Question

What is the need for laminating the core of a transformer?

• A. To reduce the resistance in the winding
• B. To reduce the eddy currents
• C. To reduce the hysteresis
• D. None of the above

Hint:

Eddy currents are circular currents induced within conductors by a changing magnetic field, causing energy loss. Laminating the core breaks these paths and reduces the loss.

Answer 1

The Correct Option is B

The core of a transformer is laminated to minimize eddy current losses.
Laminating the core increases the electrical resistance and restricts the flow of eddy currents, thereby reducing power losses and improving efficiency.
