Abstract
We have measured the electrical resistivity of sintered polycrystallin e YBa2Cu3O7-x. The current density was varied from 0.1A/cm(2) to 5.5A/ cm(2) in steps. The 50 percent resistive superconducting transition te mperature T-c(50%) was found to be 89.5K for a current density of O.1A /cm(2). With increase in current density, T-c was found to reduce and simultaneously the superconducting transition width was found to incre ase. The transition region was also found to become more asymmetric ac ross the T-c(50%) with increase in current density.
