The corresponding noise spectrum is obtained in detail for diffusive systems. It is found to be quadratic in the applied voltage and to exhibit a power-law frequency spectrum whose exponent depends on the dimensionality of the sample.4 pages, LaTex, 2 PostScript figures includedMesoscale and Nanoscale Physicstext
