For given applied voltage, with the increase in frequency of the applied voltage?
Correct answer: C. eddy current loss will remain unchanged
- A. eddy current loss will decrease
- B. eddy current loss will increase
- C. eddy current loss will remain unchanged
- D. none of the above
Explanation
With applied voltage fixed, core flux is approximately proportional to 1/frequency. Since eddy-current loss is proportional to f²B², the frequency increase and flux decrease cancel, leaving the loss approximately unchanged.
