Q.The power factor of a lightly loaded induction motor is quite low because

  • AThe current drawn is largely a magnetizing current due to air gap
  • BOf the current due to air gap
  • CThe current drawn is largely a magnetizing component due to laminated core
  • DThe current drawn is largely an energy component due to laminated core
Correct Answer : (A)

The current drawn is largely a magnetizing current due to air gap

Hints :

The power factor of a lightly loaded induction motor is quite low because The current drawn is largely a magnetizing current due to air gap.
