The open circuit voltage of a compound generator is 250 V. At full load the terminal voltage____________?
Correct answer: C. may be greater or less than 250 V
- A. will be less than 250 V
- B. will always be 250 V
- C. may be greater or less than 250 V
- D. none of the above
Explanation
The full-load voltage depends on the compounding: a cumulatively compounded generator may maintain or raise voltage, while a differentially compounded one usually suffers a drop. Therefore the terminal voltage may be either greater or less than the no-load value.
