Question

1.8 Losses that occurs in the armature winding due to reversal of magnetization of the core.

(a) Eddy current losses

(b) copper losses

(c) Hysteresis losses

(d) mechanical losses ​

Answer 1

Answer:

(c) Hysteresis losses

Explanation:

Hysteresis loss. Losses that occur when the AC primary current reverses direction. This is because the transformer core cannot change the direction of the magnetic flux immediately (slow response of core material.)
