Q: If the resistivity of a superconductor is zero, what can be said about its resistance?
Solution: A superconductor has zero resistivity, which means it has zero resistance.
Steps: 4
Step 1: Understand what resistivity means. Resistivity is a property of a material that indicates how much it resists the flow of electric current.
Step 2: Know that resistance is related to resistivity. Resistance is how much a material opposes the flow of electric current, and it depends on resistivity.
Step 3: Recognize that if a material has zero resistivity, it means it does not resist the flow of electric current at all.
Step 4: Conclude that if the resistivity is zero, then the resistance must also be zero, because no resistance means no opposition to current flow.
