Which outcome occurs when exceeding critical current in NbTi?

A)Abrupt return to normal resistance
B)Increased magnetic field penetration depth
C)Enhanced Cooper pair formation overall
D)Proportional incremental resistance increase

💡 Explanation

Exceeding the critical current causes an abrupt return to normal resistance because the superconductivity is achieved via the Meissner effect; a high current density surpasses the material's ability to maintain zero resistance by expelling magnetic fields, therefore resistance suddenly appears, rather than other gradual changes.
