Q.Due to magnetic saturation, the flux per pole in a dc machine without brush shift

  • AIncreases in both the generators and the motors with load
  • BIncreases in both the generators and the motors with load
  • CIncreases in generators but decrease in motors with loads 
  • DDecreases generators and increases in motors with load
Correct Answer : (B)

Increases in both the generators and the motors with load

Hints :

Due to magnetic saturation, the flux per pole in a dc machine without brush shift Increases in both the generators and the motors with load.
