To control the plate to cathode current

Vedclass · Answer

(B) triode valve consists of three electrodes: the cathode,the anode (plate),and the control grid. The control grid is placed between the cathode and the anode. By applying a negative potential to the grid relative to the cathode,it creates an electric field that opposes the flow of electrons from the cathode to the anode. Thus,the grid acts as a gate to control the magnitude of the plate current.
