Resistivity is the ability of a material to resist the flow of electric current. In order to understand this intrinsic property, multiple wires were placed on a resistivity apparatus to measure the resistance of the different wires, which were composed of different diameters as well as materials. The resistance of each wire was an important aspect to be able to understand the resistivity of the wire due to the fact that resistance is directly proportional to the resistivity of each wire, as it can be depicted in the following formula: P = PL A R where R is the resistance, p is the resistivity of the wire, L the length, and A is the cross-sectional area of the wire. To evaluate the cross-sectional area of the wire, the following equation was utilized: A = = π(2) ², where d is the diameter of the wire which was measured using a micrometer.
