MIXED-TYPE TOPOLOGICAL FORMULAS FOR GENERAL ELECTRICAL NETWORKS.

″Topological formulas″ are derived for the most general type of linear electrical networks, in which the characteristics of branches are expressed partly in terms of impedances and partly of admittances, and in which arbitrary branches may mutually be coupled. Derivation is direct in the sense that only the fundamental laws in network theory, i. e. , Kirchhoff's two laws and the immittance characteristics, are considered. The simplest means of deriving the existing topological formulas would be to determine them as special cases of the authors' formulas.
