← ScienceWhich mechanism causes zero electrical resistance in superconducting coils?
A)Cooper pairing of charge carriers✓
B)Increased lattice phonon scattering
C)Magnetic domain boundary pinning
D)Enhanced electron tunneling probability
💡 Explanation
Superconductivity arises from Cooper pairing, where electrons form pairs due to phonon-mediated attraction, therefore a condensate forms that conducts without loss, rather than normal resistance relying on electron-phonon interaction or magnetic effects.
