The internal efficiency of a mercury arc rectifier depends on___________?
Correct answer: A. voltage only
- A. voltage only
- B. current only
- C. voltage and current
- D. r.m.s. value of current
- E. none of the above
Explanation
Internal efficiency is mainly determined by the ratio of the useful rectified voltage to the supply voltage, so it depends primarily on voltage. The current-related terms largely cancel when the efficiency ratio is formed.
