What happens to the resistivity of a superconductor as it approaches absolute zero?

What happens to the resistivity of a superconductor as it approaches absolute zero?

Step 1: Understand what resistivity is. Resistivity is a measure of how strongly a material opposes the flow of electric current.
Step 2: Learn about superconductors. Superconductors are special materials that can conduct electricity without any resistance when they are cooled to very low temperatures.
Step 3: Know what absolute zero is. Absolute zero is the lowest possible temperature, which is 0 Kelvin or -273.15 degrees Celsius.
Step 4: Observe the behavior of superconductors as they are cooled. As a superconductor gets closer to absolute zero, its resistivity decreases.
Step 5: Conclude that at absolute zero, the resistivity of a superconductor becomes zero. This means it can conduct electricity perfectly without any loss.

Superconductivity – Superconductors exhibit zero electrical resistivity below a certain critical temperature, which approaches absolute zero.
