Answer 1

The answer is control grid.

The amplification produced by a triode is due to the action of control grid. A triode has three electrodes that are mounted inside an evacuated glass or metal container. These three electrodes comprise a cathode filament, a control grid and an anode plate. Among them, the control grid is the most critical and important electrode because of the amplification factor.
