Abstract: The equivalent resistance between any nodes of n step network is studied through analysis of network.A model of matrix transform is constructed and a constraint equation on the basis of boundary condition is established.Meanwhile,we work out a fundamental formula of equivalent resistance between any nodes of n step network,and compare different situations of the formula with other conclusions.

Key words: n step network, matrix transform, boundary condition, equivalent resistance, general formula
