The work analyzes the temporal variation of mean current and mean square current for Gaussian fluctuations of conductivity. The relaxation times for the mean current and mean square current are determined. The correlation between the fluctuations of electric current and conductivity is derived. The limits of validity of white noise approximation are discussed.
