Final answer:

The resistance of two wires made of pure copper at the same temperature and voltage can differ due to their length, cross-sectional area, and resistivity.

Step-by-step explanation:

In the given scenario, two wires made of pure copper have different resistances at the same temperature and with the same voltage applied at their ends. The wires may differ in:

  • Length: The longer the wire, the greater its resistance.
  • Cross-sectional area: The larger the cross-sectional area, the lower the resistance.
  • Resistivity: Different types of materials have different resistivities, which affect the overall resistance.

The amount of electric current passing through the wires does not contribute to the difference in resistance.
