Suppose you a have superconducting loop connected to a 9V battery. What is the current through it? With a resistance of 0Ω, [itex]V = IR[/itex] gives ∞. I don't think that can be right... If it were, [itex]V=\frac{I}{nAe}[/itex] would give an infinite velocity... Does that equation even apply to superconductors?
