← ScienceWhich mechanism reduces resistance in superconducting transmission lines?
A)Cooper pair quantum phase coherence✓
B)Increased electron-phonon scattering
C)Suppressed magnetic domain fluctuations
D)Enhanced thermal energy dissipation
💡 Explanation
Cooper pair quantum phase coherence eliminates scattering because electrons form pairs moving in a coordinated quantum state exhibiting macroscopic quantum phase coherence. Therefore, it reduces electrical resistance, rather than increased scattering or other normal conductance limits.
