A 220/440 V, 50Hz, 5kVA single phase transformer operates on 220V, 40 Hz supply with secondary winding. Then

1. The eddy current loss and hysteresis loss of the transformer decrease
2. The eddy current loss and hysteresis loss of the transformer increase
3. The hysteresis loss of the transformer increases while eddy current loss remains the same
4. The hysteresis loss remains the same whereas eddy current loss decreases
