As a result, the tw electrns, are bund int an entity called a Cper pair. The Cper pair behaves like a bsn (= particle with integral spin that d nt bey the Pauli exclusin principle). At very lw temperature, it is pssible fr all bsns in a cllectin f such particles t be in the lwest quantum state. As a result, the entire cllectin f Cper pairs in the metal is described by a single wave functin. Abve the energy level assciated with this wave functin is an energy gap equal t the binding energy f a Cper pair. Under the actin f an applied electric field, the Cper pairs experience an electric frce and mve thrugh the metal. A randm scattering event f a Cper pair frm a lattice in wuld represent resistance t the electric current. Such a cllisin wuld change the energy f the Cper pair because sme energy wuld be transferred t the lattice in. But there are n available energy levels belw that f the Cper pair (it is already in the lwest state) and nne available abve, because f the energy gap.
