Anoble Vol+age Fig. 17. this line is seldom horizontal but usually slopes upward. Thispart of the curve corresponds to the condition when all the emittedelectrons are drawn to the anode as fast as they are emitted fromthe cathode. The corresponding current is, therefore, the satura- … Catnode Tempera+ure Fig. 18. tion current. If the temperature of the cathode be increased toT2 the curve OA2B2 will be obtained. If these values of thesaturation current be plotted against the corresponding tempera-tures of the cathode, the curve shown in Fig. 18 will be obtained, 52 THERMIONIC…
