The normal resistance of SN-N-NS Josephson contacts has been calculated in the case of setting a measurement current in the N film of the structure. Expressions have been obtained for the characteristic lengths of current redistribution in the SN electrodes at temperatures greater than and less than the critical temperature of the structure's transition to the superconducting state. A method for experimentally determining these lengths has been proposed. It is based on measuring the dependence of the contact's normal resistance on the width of its S electrode. Keywords: SN-N-NS Josephson junction, normal resistance, conversion lengths.
