In selenium rectifiers efficiencies ranging from _______ to _______ percent are attainable?
Correct answer: D. 75, 85
- A. 25, 35
- B. 40, 50
- C. 60, 70
- D. 75, 85
Explanation
Selenium rectifiers typically achieve efficiencies in the approximate range of 75 to 85 percent. Their losses are higher than those of modern silicon rectifiers, which is why the efficiency is not near 95 percent.
