Steel is an alloy, consisting of iron and carbon. It has many metallic properties, which change with variations in the amount of carbon. Differences in quantity and placement of carbon in the alloy changes the hardness and strength of the ensuing steel; with increasing amounts of carbon, steel can become even stronger and harder than iron.

Electrical resistivity can be found by measuring how strongly a material withstands the flow of an electrical current. if a material has low resistivity, then it is easier for electricity to flow through this material. the SI unit for resistivity is the ohm meter, Ωおめがm. Electrical resistivity is represented by the Greek letter rho, ρろー. The static resistivity of a material is equal to its electrical resistivity multiplied by the cross-sectional area of the sample divided by the length of the sample

R=ρろーl/A

According to Ohm's Law, the electrical resistance of a conductor is equal to the potential difference, or voltage drop between two connected points in a conductor, divided by the flow of electrical current in the conductor. The resistivity of steel is on the order of 10-6 Ωおめがm.
