Glass rectifiers are usually made into units capable of D.C. output (maximum continuous rating) of _____________?
Correct answer: E. 500 A at 500 V
- A. 100 A at 100 V
- B. 200 A at 200 V
- C. 300 A at 300 V
- D. 400 A at 400 V
- E. 500 A at 500 V
Explanation
Glass mercury-arc rectifiers were commonly manufactured for high-current, high-voltage service, with standard maximum continuous ratings reaching about 500 A at 500 V. The smaller ratings do not represent the usual maximum rating asked here.
