In a mercury pool rectifier, the voltage drop across its electrodes___________?
Correct answer: D. is almost independent of load current
- A. is directly proportional to load
- B. is inversely proportional to load
- C. varies exponentially with the load current
- D. is almost independent of load current
Explanation
The arc and electrode voltage drops in a mercury pool rectifier remain nearly constant over its normal operating-current range. Thus, the total electrode voltage drop is almost independent of load current.
