Limiting diffusion currents toward the rotating disc electrodes are determined theoretically for the cases of low Reynolds numbers, Re < 10, and for viscoelastic liquids with non-zero normal stress differences, Ab > 0. The case of Newtonian fluid, Ab = 0, at low Re is considered in details and is tested by comparing the theoretical prediction with experimental data.
