Experiment 2 Datasheet Name:_________________ Section: _________ Note: For the “unknown” resistance, R, just use the 4.7 k resistor. Ohm’s Law with Fig. 2.3 V s (V) I R (mA) V R (V) -10 -5 0 5 10 Plot V R v. I R on the next page. From examination of the plot, what is the unknown resistance, R? How did you arrive at this figure for R? Does the plot go through the origin? Should it? Why or why not? Ohm’s Law with Fig. 2.4 V s (V) I (mA) V (V) -10 -5 0 5 10 Plot V v. I on the next page. From examination of the plot, what is the unknown resistance, R? How did you arrive at this figure for R? Does the plot go through the origin?

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
