The voltage drop at anode, in a mercury arc rectifier is due to_____________?
Correct answer: C. energy spent in overcoming the electrostatic field
- A. self restoring property of mercury
- B. high ionization potential
- C. energy spent in overcoming the electrostatic field
- D. high temperature inside the rectifier
Explanation
Anode drop occurs because charged particles must expend energy in overcoming the electrostatic field near the anode. It is therefore associated with the anode field rather than with temperature or mercury self-restoration.
