Exciters of synchronous machines are______________?
Correct answer: B. d.c. shunt machines
- A. d.c. series machines
- B. d.c. shunt machines
- C. d.c. compound machines
- D. any of the above
Explanation
Traditional synchronous-machine exciters are generally d.c. shunt generators because they provide a controllable, nearly constant field current. Modern machines may use brushless or static exciters, but those are not among the options.
