- A$30K$
- ✓$40K$
- C$50K$
- D$60K$
✓
Answer
Correct option: B.
$40K$
Bell laboratory has developed superconductor at a temperature of $40 K$.Superconductivity is a phenomenon of exactly zero electrical resistance and expulsion of magnetic flux fields occurring in certain materials, called superconductors, when cooled below a characteristic critical temperature. It was discovered by Dutch physicist Heike Kamerlingh Onnes on April $8, 1911$, in Leiden.
