The resistance of an electrical conductor depends on several factors. Its physical shape is one factor. The type of conductor material is another, as might be expected. That is, two conductors with the same physical shape, but of different materials, have different resistances. This important material characteristic of resistance is expressed in terms of a quantity called resistivity.

The ILS shows you how you can do resistance and resitivity measurements in the lab and you will understad how would change the resistance of a wire conductor If the length were to double or the Area were to double.
