Superconductors vs Ideal conductors
An Ideal Conductor is a theoretical construct, available only in simulators and theory. It has zero resistance, zero inductance, zero capacitance to ground, can carry an infinite current, can support an infinite voltage difference to any adjacent conductors, and has zero electrical length.
An ordinary copper wire approximates those features, more or less well, depending on length, cross section, purity, insulation material round it.
A superconductor has zero resistance, and approximates the rest of those features, more or less well, depending again on its physical characteristics.
