If the frequency of input voltage of a transformer is increased keeping the magnitude :

If the frequency of input voltage of a transformer is increased keeping the magnitude of voltage unchanged, then:

  1. hysteresis loss will decrease but eddy current loss will increase
  2. hysteresis loss will increase but eddy current loss will decrease
  3. hysteresis loss will decrease but eddy current loss will remain unchanged
  4. both hysteresis loss and eddy current loss in the core will increase
