A Transformer is working at its maximum efficiency. Its iron loss is 1 kW. Its copper loss will be

Right Answer is:

1 kW

SOLUTION

The efficiency of the transformer will be maximum at a load in which the total copper loss in the windings is equal to the core-loss

Since the Iron loss is 1 kW, therefore, the core loss will be also equal to 1 kW
