A transformer core is laminated to__________?
Correct answer: B. reduce eddy current losses
- A. reduce hysteresis loss
- B. reduce eddy current losses
- C. reduce copper losses
- D. reduce all above losses
Explanation
Thin insulated laminations interrupt the circulating paths in the iron core, thereby reducing eddy-current loss. Hysteresis loss depends mainly on the core material and magnetic flux conditions, not simply on lamination.
