The efficiency of a transformer will be maximum when
A)copper losses = hysteresis losses
B)hysteresis losses = eddy current losses
C)eddy current losses = copper losses
D)copper losses = iron losses

Question

Quizplus · Accepted Answer

The efficiency of a transformer is maximum when copper losses (losses due to the resistance of the winding) are equal to iron losses (combined hysteresis and eddy current losses in the core). This balance ensures that the transformer operates at its most efficient point.
