The thermionic vacuum tube and its applications (1920)
Van der Bijl, Hendrik Johannes, 1887- · New York McGraw-Hill Book, Co · leaf 146
he valve now depends upon its resistance andthe load resistance r. Suppose that r is initially so large that thevoltage drop E in the valve is less than the optimum voltage Eg.If r be now decreased the current increases and the voltage drop inthe rectifier also increases. How this change takes… … 1 S. DusHMAN, General Electric Review, loo. cit. r = i^o__i_ 124 THERMIONIC VACUUM TUBE current and E the voltage drop in the valve we have E = Eo—IrPutting/ = C£we get: l(Eo_J CyE E This shows that as r is decreased the voltage chop E in the valveincreases slowly at first and then more rapidly.…
