7. Constancy of a Resistor Score: /5 a. Vary the voltage across your resistor from V=0V to at least V=10V. Measure the current going through the circuit in each case and record your data on a table of V and I values with uncertainties for both measurements. b. Plot your Vvs. I data (using graph paper or Excel). A straight line should reasonably t your data. Use it to determine the resistance. Attach the plot after this page. c. Compare the resistance you found from your plot with the one directly measured with an Ohmmeter (question 4). Calculate a percent difference between the two values
