nometer circuitto measure the input voltage. The key K should therefore beopened when the galvanometer is connected to the input and closedwhen it is connected to the output of the tube. Results obtained by my associate, Mr. R. H. Wilson, are givenin Fig. 211, which shows the relation between the… … Fig. 210. straight part. The values shown m this figure were obtained byreducing the obsei-vations to a common value to superimpose thecurves on one another. For each of these grid voltages the voltageof the plate battery was adjusted to maintain the space currentconstant. In other words, the…
