![]() Note, there are brass wires with four different diameters. Go through Pasco’s Resistance Manual and record the resistivity and the diameter of the wire for each of the following three materials. You have unlimited attempts, but you must get perfect score. If you have not worked with multimeters before, go to the Instrumentation page and become familiar with how they work.Īssignment: Take the following safety quiz. To be able to find relevant information by reading through equipment manuals.To learn how to plot experimental data and interpret the graph in physics terms.To learn how to use linear regression to fit experimental data.To learn how to organize and analyze experimental data in spreadsheets.To learn how to use Ohm’s Law to determine the resistivity of an object.To determine how the resistivity depends on the length and the cross sectional area of the resistor.
