Abstract

We discuss the peculiarities of the Ohm law in dilute polyelectrolytes containing a relatively low concentration n of multiply charged colloidal particles. It is demonstrated that in these conditions, the effective conductivity of polyelectrolyte is the linear function of n. This happens due to the change of the electric field in the polyelectrolyte under the effect of colloidal particle polarization. The proposed theory explains the recent experimental findings and presents the alternative to mean spherical approximation which predicts the nonlinear I-V characteristics of dilute colloidal polyelectrolytes due to entropy changes.
