← ScienceWhich mechanism enables lossless power transmission in superconducting transmission lines?
A)Meissner effect expelling magnetic fields✓
B)Increased electron-phonon scattering events
C)Decreased Cooper pair binding energy
D)Elevated electron-electron repulsive forces
💡 Explanation
The Meissner effect expelling magnetic fields causes zero resistance in superconducting lines because it prevents magnetic flux penetration and energy dissipation; therefore lossless transmission occurs, rather than lossy transmission from magnetic field interaction or changes in Cooper pairing.
