The efficiency of the copper oxide rectifier seldom exceeds____________?
Correct answer: D. 65 to 75%
- A. 90 to 95%
- B. 85 to 90%
- C. 80 to 85%
- D. 65 to 75%
Explanation
Copper oxide rectifiers have relatively high forward voltage loss and limited current capability, so their efficiency seldom exceeds roughly 65 to 75 percent. The higher ranges are more typical of better semiconductor rectifiers.
