Abstract
We calculate the resistance of one-, two-, and three-dimensional local ized systems in the hopping regime, simulated by random-resistor netwo rks within the r-resistor model. The analysis of the logarithm of the resistance as a function of the degree of spatial disorder reveals tha t in one- and two-dimensional samples the resistance increases with di sorder, while in three-dimensional samples the resistance decreases. W e also study the fluctuations of the conductance from sample to sample .
