← ScienceWhich mechanism explains sharply reduced impedance in superconducting materials?
A)Cooper pair formation✓
B)Increased electron scattering
C)Phonon absorption increase
D)Increased lattice vibrations
💡 Explanation
Materials achieve zero DC resistance through Cooper pair formation because electrons pair up; therefore they move without energy dissipation rather than experiencing impedance like regular electrons since electron-phonon interaction links them.
