Question

Superconductivity is

• A. the property of which certain materials show almost zero resistance at 1000 ${}^{0}C$.
• B. the property of which certain materials show almost highest resistance at very high temperature
• C. the property of which certain materials show almost zero resistance at very low temperature
• D. the property of which certain materials show almost zero resistance at very high temperature

Answer 1

The correct option is C the property of which certain materials show almost zero resistance at very low temperature

Superconductivity is the property of a substance when its resistance abruptly decreases to zero at low temperature.

Answer-(C)
