A series generator can self-excite:______________?
Correct answer: B. only if the load current is not zero
- A. only if the load current is zero
- B. only if the load current is not zero
- C. irrespective of the value of load current
- D. none of the above
Explanation
A series generator needs load current to flow through its series field winding before that winding can build useful flux and voltage. With zero load current, the series field is effectively unenergised, so self-excitation cannot occur.
