Question

The grid in a triode is kept negatively charged to prevent...

-the variations in voltage from getting too large
-the electrons from being attracted to the grid instead of the anode
-electrons from escaping from the tube containing the triode

Answer 1

B. the electrons from being attracted to the grid instead of the anode.

Step-by-step explanation:

just because its the answer

Answer 2

I think the correct answer is the third statement, electron from escaping from the tube containing the triode. The negative charge on the grid repels any electron in the tube. As a result,the flow of current is controlled. If the field is that strong, all current flow will stop resulting to maintaining the electron cloud in the tube.
