Physics · Superconductivity
How does the electrical resistance of a superconductive material change when its temperature drops below the critical temperature (Tc)?
- 1It remains constant at a non-zero residual value.
- 2It increases suddenly due to electron pairing.
- 3It drops abruptly to exactly zero.✓
- 4It decreases linearly to half of its initial value.
Correct answer
It drops abruptly to exactly zero.
