In a grid control of mercury arc rectifiers when the grid is made positive relative to cathode, then it the electrons on their may to anode.
Correct answer: A. accelerates
- A. accelerates
- B. decelerates
- C. any of the above
- D. none of the above
Explanation
A grid made positive with respect to the cathode attracts electrons and increases their velocity towards the anode. Thus, it accelerates the electrons and promotes arc conduction.
