In a transformer, the hysteresis and eddy current losses
depend upon
1.load current
2.maximum flux density in core
3.type of lamination
4.supply frequency
The correct statements are
(a) 1 and 3 (b) 2 and 3
(c) 1 and 4 (d) 2 and 4

Answer Posted / bunny

3 & 4 as loss is directly proportional to square of f nd
thickness of lamination
