Q.In a dc machine, the brushes are physically placed in the 

  • APolar axis and electrically connected to the coils lying in the interpolar axis
  • BPolar axis electrically connected to the coils lying in the polar axis 
  • CInterpolar axis and electrically connected to the coils lying in polar axis 
  • DInterpolar axis and electrically connected to the coils lying in interpolar axis 
Correct Answer : (A)

Polar axis and electrically connected to the coils lying in the interpolar axis

Hints :

In a dc machine, the brushes are physically placed in the Polar axis and electrically connected to the coils lying in the interpolar axis.
