Critical currents of granular Al bridges with different thicknesses and widthshave been measured as a function of temperature. The experimental values ofcritical current were somewhat smaller than the pair-breaking current in theGinzburg-Landau theory, being proportional to (T. -T)"' near the criticaltemperature T.. Irz the lower temperature region they became to be proportional to(7'. -T). It was found from the temperature atad thickness dependences thatcritical current seems to be governed by the mechanism, different from thepair-breaking one.Slightly below T., appearance of electrical resistance was observed, dependingon the bridge thickness, but not on its width. It is suggested that vortices arethermally activated and their flow generates a voltage.
