Selenium rectifier can be operated at temperatures as high as____________?
Correct answer: D. 75°C
- A. 25°C
- B. 40°C
- C. 60°C
- D. 75°C
Explanation
Selenium rectifiers can withstand considerably higher temperatures than copper oxide rectifiers, with operation possible up to approximately 75°C. Temperature limits still depend on the particular construction and cooling conditions.
