Which of the following D.C. generators will be in a position to build up without any residual magnetism in the poles?
Correct answer: D. None of the above
- A. Series generator
- B. Shunt generator
- C. Compound generator
- D. None of the above
Explanation
Self-excited series, shunt, and compound generators need residual magnetism to initiate the initial generated emf and field current. Without residual magnetism, none of these listed self-excited generators can normally build up voltage.
