Examples

As the voltage applied to the so-called control grid (or simply "grid") was lowered from the cathode's voltage to somewhat more negative voltages, the amount of current from the filament to the plate would be reduced. Source: Internet

The control grid and screen grid are also wound with the same pitch, or number of wires per inch. Source: Internet

In a monochrome receiver the luminance signal is amplified to drive the control grid in the electron gun of the CRT. Source: Internet

Many devices have other electrodes to control operation, e.g., base, gate, control grid. Source: Internet

When held negative with respect to the cathode, the control grid creates an electric field which repels electrons emitted by the cathode, thus reducing or even stopping the current between cathode and anode. Source: Internet
