As can be seen from the figure, the length, cross-sectional area and material of the two wires are different, so we can explore the relationship between resistance and conductor material, resistance and conductor length, and resistance and conductor cross-sectional area.

So the answer is whether the conductor resistance is related to the conductor material.
