The grid in a high-vacuum triode is usually kept negatively charged with respect to the cathode so that the electrons may be? A)accelerated toward the anode. B)accelerated toward the cathode. C)attracted to the anode instead of the grid. D)attracted to the cathode instead of the grid.
C)attracted to the anode instead of the grid.

attracted to the anode instead of the grid.
The correct answer is D) attracted to the cathode instead of the grid.
To answer this question, let's break down the options:
A) Accelerated toward the anode: This is not the correct answer because the electrons are not accelerated toward the anode in a high-vacuum triode. The correct answer involves the behavior of electrons in relation to the grid and the cathode.
B) Accelerated toward the cathode: This is also not correct because the electrons would not be accelerated toward the cathode in a high-vacuum triode.
C) Attracted to the anode instead of the grid: This is the correct answer. In a high-vacuum triode, the negative charge on the grid repels the electrons and prevents them from reaching the anode, so they are attracted to the anode instead of the grid.
D) Attracted to the cathode instead of the grid: This is not the correct answer because the electrons are not attracted to the cathode instead of the grid in a high-vacuum triode.
So, the correct answer is C) attracted to the anode instead of the grid.
