Ageing of a selenium rectifier may change the output voltage by__________?
Correct answer: A. 5 to 10 per cent
- A. 5 to 10 per cent
- B. 15 to 20 per cent
- C. 25 to 30 per cent
- D. none of the above
Explanation
Ageing in selenium rectifiers gradually changes the selenium junction characteristics, commonly producing about a 5 to 10 percent change in output voltage. This ageing effect is a major limitation of selenium devices.
