← ScienceWhich consequence occurs when the applied voltage in a Josephson junction exceeds a critical threshold?
A)Quantized voltage appears because AC Josephson effect✓
B)Supercurrent decreases because of the proximity effect
C)Increased resistance because of Cooper pair formation
D)Increased inductance minimizes current oscillation
💡 Explanation
AC Josephson effect creates an oscillating supercurrent, producing quantized voltage steps. Therefore, quantized voltage steps exist, rather than inductance changes or resistance increases, because, at lower voltage, only DC current flows.
