Abstract
We study the effects of an electric field in the transport properties of bulk granular superconductors with different kinds of disorder. We find that for a d-wave granular superconductor with random π junctions the critical current always increases after applying a strong electric field, regardless of the polarity of the field. This result plus a change in the voltage as a function of the electric field are in good agreement with experimental results in ceramic high Tc superconductors.
