The current-voltage characteristics (CVCs) of YBa2Cu3O6.95 ceramic samples were measured in Hext (0 < Hext < 500 Oe) magnetic fields. The CVCs of the samples magnetized in Htreat magnetic fields were measured at Hext = 0. Based on the CVCs, Ro(j),Hext=const , Ro(Hext),j=const and Ro(j),Htrap=const dependences were reestablished. The comparative analysis of Ro(j) and Ro(Hxt) dependences indicates the magnetic field redistribution between grain boundaries and superconductive granules influence on transport and galvanomagnetic properties of granular HTS. The superconductive grain magnetoresistance Rog was established to be significantly lower than RoJ value of Josephson medium. Pages - 24, Fig. - 11, References - 42.
