The thickness of laminations used in a transformer is usually____________?
Correct answer: A. 0.4 mm to 0.5 mm
- A. 0.4 mm to 0.5 mm
- B. 4 mm to 5 mm
- C. 14 mm to 15 mm
- D. 25 mm to 40 mm
Explanation
Transformer core laminations are typically about 0.35 to 0.5 mm thick, matching the 0.4 to 0.5 mm range given. Thin laminations reduce circulating eddy currents and hence core loss.
