n that a three-electrode tube may be thoughtof as a variable resistance, the setting of which depends uponthe grid voltage. The higher the grid voltage, the less is theresistance, and vice versa. For low grid voltages on this dia-gram the resistance changes mth plate current in a manner… … -^ -I.O 0.6 0.6 Off- O.Z -O-^ OZ 0.4- 0.6 0.3 /.o. increasing current. This conception of a tube is very helpful in studying its operation, especially in transmitting equipment. The resistance of the tube can not be clianged without the dissipation of power in the grid-filament circuit. The amount…
