Q1:- what is meant by the leakage flux of transformer
1. It is the flux which is linked with the primary and the secondary winding
2. It is that part of the magnetic flux which is significant for radio interference
3. It is the magnetic flux which is linked the only with the primary or only with the secondary winding
4. The leakage flux in the transformer is the influx whose path is exclusively through the air
Q3:- hysteresis loss in a transformer depends upon the
1. Applied voltage
2. Type of core material
3. Number of laminations
4. Reactance of the winding
ANSWER:-2
