The temperature dependence of the out-of-plane and in-plane resistance of a c-axis-oriented (Bi,Pb){sub 2}Sr{sub 2}Ca{sub 2}Cu{sub 3}O {sub x} silver-sheathed tape with high critical current density (J{sub c}{gt}2{times}10{sup 4} A/cm{sup 2}, 77 K, 0 T) has been investigated under applied fields up to 0.9 T. It is found that the in-plane and the out-of-plane resistance transitions are quite different: (1) The out-of-plane zero resistance temperature is much higher than the in-plane one, i.e., T{sub c}{sup ab}(H){lt}T{sub c}{sup c}(H), and the difference increases with magnetic field; (2) the out-of-plane zero resistance temperature corresponds to the c-axis decoupling temperature. These phenomena are attributed to different dissipation mechanisms. The in-plane dissipation at low temperature results from the thermally activated flux{endash}flow, while the out-of-plane dissipation originates from the Josephson junction dissipation of weakly coupled c-axis grain boundaries and/or intrinsic Josephson junctions.{copyright} {ital 1997 American Institute of Physics.}
