MCQ
Bell laboratory has developed superconductor at a temperature of:
- A30K
- B40K
- C50K
- D60K
✓
Answer
- 40K
Explanation:
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.
