8. Superconductors have __________ a) Almost zero resistivity b) Very high resistivity c) Temperature-dependent resistivity d) Moderate value of resistivity
Answer: a Explanation: Semiconductors are those which carry current with almost zero resistivity at a very low temperature (example: Lead at -272-degree centigrade). So, they have a very huge amount of current flow through them.
Superconductors have almost zero resistivity
