The 0-∞ method proposed in this paper is a method which solves the network problem by making use of the relations among the determinants of the network and its modifiers.The main merit of the method is simplicity of the rules used. From the appearance of the network

the existing voltage and current transmissions and the driving-point impedances may be found directly without resorting to the network determinants. Necessary theorems and examples were given.The 0-∞ method is limited to linear passive lumped reciprocal netwoks without transformers. Under this restriction

the 0-∞ method has a series of advantages in comparison with some topological methods

such as signal flow graphs and the tree-method.
