The desirable properties of transformer core material are
- A. Low permeability and low hysteresis loss
- B. High permeability and high hysteresis loss
- C. High permeability and low hysteresis loss
- D. Low permeability and high hysteresis loss
Answer: C. High permeability and low hysteresis loss
Explanation: Transformer core materials should have high permeability to easily establish magnetic flux with minimal magnetizing current, and low hysteresis loss to reduce heat dissipation generated during alternating magnetic cycles.
