Which of the following loss in a transformer is zero even at full load ____________?
Correct answer: B. Friction loss
- A. Core loss
- B. Friction loss
- C. Eddy current loss
- D. Hysteresis loss
Explanation
A transformer has no rotating mechanical parts, so it has no friction loss even at full load. Core, hysteresis, and eddy-current losses remain present during operation.
