A 250 V dc generator is run at rated speed with no excitation. The open circuit voltage will be

  • AZero
  • BVery small, say about 2 or 3 V 
  • CAbout 100 V
  • D250 V
Correct Answer : (B)

Very small, say about 2 or 3 V 

Hints :

Torque developed in an electromechanical energy conversion device depends upon


In electromechanical energy conversion devices (e.g generators and motors) a small air gap is left between the stator and the rotor in order to
