Discussion

Understanding the dc generator remains useful because

  • A.it is still the commonest source of direct current in industry
  • B.its construction is identical to that of an induction machine
  • C.no other machine has a magnetisation curve worth studying
  • D.its relations underlie dc motor and converter behaviour

Answer: D

The emf equation, the magnetisation curve, armature reaction and commutation all reappear in the dc motor and in the drives built around it. It is also the clearest possible illustration of self-excitation and its conditions.
