Flip the equation and think of it as I = V/R As resistance nears zero, the current becomes infinite, regardless of the voltage.

- acchow 10y agoOf course, the current isn't infinite in a superconductor... In short, V=IR is a simple model and doesn't apply to superconductors (as mentioned in other comments above)
- agarttha 10y agoA superconductor is not a resistor. It is an ideal inductor. Ohm's law doesn't apply. You have Phi = LI instead of V = IR, where Phi is the magnetic flux generated by a superconducting wire of inductance L.
