This is why super-conductors float above magnets
because there's no resistance
If you offer no resistance to something at all, it will happily flow infinitely and cause no side-effects
Luckily normal materials, such as copper, aluminium, steel, rubber, bathroom tiles, shoe-laces and human bone all have a defined resistance per unit length for a given cross-section, so in normal, every day life there's not much infinite current or zero voltage malarkey
Even if some of the things in my list have averages and standard deviations and others are relatively well defined, they all belong there
