← ScienceWhich failure impacts a superconductor exposed to substantial electrical current?
A)Resistance increase above zero✓
B)Electron tunneling rate decline
C)Critical temperature elevates unexpectedly
D)Meissner effect becomes magnified
💡 Explanation
When current exceeds a limit, the Cooper pairs break, causing resistive behavior via flux penetration, because exceeding the critical current disrupts superconductivity. Therefore resistance increases, rather than maintain superconductivity, because of disrupted electron pairing preventing dissipation-free flow.
