The terminal voltage of a series generator is 150 V when the load current is 5 A. If the load current is increased to 10 A, the terminal voltage will be____________?
Correct answer: C. greater than 150 V
- A. 150 V
- B. less than 150 V
- C. greater than 150 V
- D. none of the above
Explanation
Increasing load current strengthens the series-field flux, so the generated emf of a series generator generally rises with load current before magnetic saturation becomes significant. Hence the terminal voltage is expected to be greater than 150 V.
