  We discuss the peculiarities of the Ohm law in dilute polyelectrolytes
containing a relatively low concentration of the multiply-charged colloidal
particles. It is demonstrated that in this conditions, the effective
conductivity of polyelectrolyte is the linear function of colloidal particles
concentration. This happens due to the change of electric field in the
polyelectrolyte under the effect of colloidal particle polarization.
  Such mechanism gives grounds to propose the alternative scenario for the
phenomenon observed experimentally.
