electromagnetism - What makes Cooper pairs of electrons so fit for an unhindered current through a superconducting wire?


When a superconducted wire is cooled close to 0K, the electrons could form a Cooper pair. They become (or behave) like bosons.


But what is meant that those electrons got the same, by which the Pauli-principle isn't an obstacle anymore?


And why should this Cooper pair have no resistance going through the wire anymore? Does it has lost his charge?
