State the equation of the resistance, R, of a piece of wire in terms of its resistivity. Briefly explain the difference between resistance, R, and resistivity, ρ.

If you have experimental data for the resistance, R, for various lengths, L, explain how you would determine the material's resistivity, ρ.
