N2 - The many experimental data that have been accumulated for the critical resistance exponent, (Formula presented) and the relative resistance noise exponent, κ, in percolation systems, are generally in disagreement with the original predictions of the random void and the inverted random void models of continuum percolation. In this paper we show that by allowing a nonrandom distribution of the voids (or the particles) in these models, one can account for all the experimental data. In particular, we show that, except for the two-dimensional inverted random void system, the exponent (Formula presented) may have any value larger than its universal value, while the (Formula presented) ratio will be bound.
