Calculations and Graphing

For each of the three previous procedures calculate the resistance from the measured current and voltage: R = V/I.

Use an x-y scatter graph to graph voltage on the y-axis versus current on the x-axis.

Use the linear fit trend line function of Excel to add the slope of the line to the graph.

What is the significance of the slope?

How do the graph and the slope of the line relate to Ohm’s law?

Can this series of experiments be considered a verification of Ohm’s law? Why or why not?
