also stated that k is a constant ELECTRONS FROM SOLID SUBSTANCES 45 depending on the grid and d the distance between grid and anode.In testing this relation the grid remained grounded while thepotential of the cathode was varied. This made it possible tokeep the potential difference V between grid… … 6u 80 100 Anode-(jriol Voltage Fig. U distance d between grid and anode was G.7 nmi., while theupper cui-ve was obtained with d = 2.o mm. If, instead of plot- V ting V as abscissse, we plot —, the two cui-ves coincide. a, It can readily be seen that if we substitute — Eg for v and Ep,the potential…
