In a superconducting ring, a persistent current has been flowing without decay for years. This is possible because
In a superconducting ring, a persistent current has been flowing without decay for years. This is possible because
Show Hint
Persistent current in a superconducting ring is possible due to zero resistance and magnetic flux quantization.
Updated On: May 7, 2026
- Resistance is exactly zero and flux is quantized
- Resistance is very high and current is quantized
- Magnetic field is zero and voltage is maximum
- Temperature is very high and resistance is finite
