← ScienceWhich mechanism explains current flow when voltage drops momentarily across superconducting wire?
A)Kinetic inductance generates momentary voltage✓
B)Flux pinning recovers magnetic stability
C)Cooper pair density briefly diminishes
D)Thermal conductivity restores equilibrium temperature
💡 Explanation
Kinetic inductance in superconductors arises because Cooper pairs possess inertia; therefore when voltage fluctuates transiently, current resists change due to this inductance, thereby briefly driving it through finite resistance phase rather than perfect conduction which would necessitate no current change.
