We discuss the nonlinear behavior of a simple cubic two-component random resistor network (RRN), in which the local current and voltage are related by I = gV + blV/'V and blV1'4g. The macroscopic nonlinear conductivity b, is expanded as a power series in the relative difference between the ohmic co
