Transformer core is laminated,
- A. because it is difficult to fabricate solid core.
- B. because laminated core provides high flux density.
- C. to avoid eddy current and hysteresis losses.
- D. to increase the main flux.
Answer: C. to avoid eddy current and hysteresis losses.
Explanation: Lamination reduces eddy-current loss (key answer lists eddy and hysteresis).
