Speed control by Ward Leonard method gives uniform speed variation_____________?
Correct answer: B. in both directions
- A. in one direction
- B. in both directions
- C. below normal speed only
- D. above normal speed only
Explanation
Ward-Leonard control varies the generator output voltage continuously, giving smooth speed control from zero through the rated speed and allowing reversal by reversing the generator output polarity. Hence uniform variation is available in both directions.
