Abstract :
This paper is an extension of the work reported in a paper of the same title by the writer and C. N. Weygandt.1 The production of subharmonic oscillations in a series circuit consisting of a capacitor and an iron-cored inductor is studied by the method of matching boundary conditions. The calculations are carried out by means of a new mechanical calculating device, and are verified by differential-analyzer solutions. A sufficient, but not necessary, criterion for stability is deduced. Some consideration is given to the effect of resistance in the circuit.
