A METHOD FOR SOLVING ELECTRIC NETWORK
一种解电路網络的方法

In this paper a method for solving electric network is suggested. By this method, the solution of the network may be found conveniently without solving simultaneous equations.This paper consists of two parts. The first part deals with the method for solving the general linear network. The procedure of which is, firstly, to replace the e.m.fs. in the network by an equivalent source of currents; secondly, to eliminate the joints of the network one by one until the network transforms into an equivalent branch for finding the potential difference between the terminals of this branch; thirdly, to restore the equivalent branch to original network for finding the potentials of all joints of the network; finally, we can calculate the currents of the branches of the network easily. The second part deals with the special method for solving the linear network which contains only one e.m.f. The difference between this method and the former one is that the proceeding of restoring the equivalent branch to original network in this method may be omitted. In order to omit this proceeding, it is necessary to assume a certain amount of current source on every joint of the network before the transformation of the network. Therefore, when the network transforms into an equivalent branch, we may find the potentials of all joints of a network which contains only one e.m.f.
