Two wires made of different materials have the same uniform current density. Both wires will have the same current only if: Select one: O the potential differences across them are the same O both their lengths and cross-sectional areas must be the same O Can never be the same because of the difference in the resistivity O their cross-sectional areas are the same O More information needed O their lengths are the same O the electric fields in them are the same
