Q.

The transformer efficiency at relatively light loads is quite low. This is due to

  • ASmall copper losses
  • BSmall secondary output
  • CHigh fixed loss in comparison to the output
  • DPoor power factor
Correct Answer : (C)

High fixed loss in comparison to the output

Hints :

The transformer efficiency at relatively light loads is quite low. This is due to High fixed loss in comparison to the output.
