For this challenge lab you will be trying to determine the resistivity of a wire based on a graph of Resistance vs. Length. You will be prompted to collect 5 different current readings using 5 different length samples of wire. You will calculate the resistance of that segment of wire using Ohm's Law and then you will plot a graph of resistance vs. length. Finally, you will measure the cross-sectional area of the wire to find the resistivity of the material that makes up the wire.

Each time you load this program you will get a randomly generated resistivity, so don't exit the program once you start.
