Question

Why do good conductors never become superconductors?

Answer 1

Superconductors are those materials which are usually bad conductors in room temperature but when the temperature is decreased to very low, the resistance becomes zero. That's why good conductors can't be transformed into superconductors.

Answer 2

Answer:

Superconductors are materials where electrons can move without any resistance. But today's superconductors don't work unless they are cooled to well below room temperature. They stop showing any electrical resistance and they expel their magnetic fields, which makes them ideal for conducting electricity.
