Q.The slight curvature at the lower end of the OCC of a self excited dc generator is due to 

  • AMagnetic inertia 
  • BResidual flux 
  • CHigh speed
  • D  High field resistance 
Correct Answer : (B)

Residual flux 

Hints :

The slight curvature at the lower end of the OCC of a self excited dc generator is due to Residual flux.
