Just as a general consideration, most (all) superconductors have a critical current beyond which they are no longer superconducting. This comes from the variations in the magnetic field generated by the current. and these variations disrupt the cooper pair flow. (So no ∞ current, not a problem) – ElderDelp. Sep 27, 2022 at 20:18.
