where Z2 is the impedance of coil 2. The mutual conductanceof the tube is then given by: that is, by rp_eg Z2 fJi 22 MTp r> h ^2 — = Ki- ^2 M (44) (44a) For a simplification of this dynamic method I am indebted toan hitherto unpublished suggestion of Mr. H. W. Everitt which is THE THERMIONIC… … Fig. 102. external resistance is shown in the following table, which givesobservations obtained by Everitt.
