24) and (25). Furthermore, /x and the plateresistance must be so chosen that the amplification has thedesired value. This is usually as large as possible. 238 THERMIONIC VACUUM TUBE There are thus a number of requirements to be satisfied and theydiffer with different operating conditions. The… … 40 60 80 100 Anode Volts-Ep Fig. 125. 120 140 and the relation between plate resistance and plate voltage, over a range of operating plate voltages. The slope — of the plate current-grid potential characteristic can then be obtaineddirectly from the known values of jx and rp. The tube shown in Fig.…
