E11: More with Resistance and Resistors Materials: Power supply, multimeter, resistors, pencil, paper, play doh, wires, switch Initial definitions and givens: Multimeter: an electrical instrument that can measure voltage, current, and resistance. When a multimeter is used as an ohmmeter to measure resistance, it is not used as part of a circuit or to measure the resistance of a battery or power supply. Initial Instructions and questions: 1. Using the multimeter, measure the resistance of the three resistors you dealt with in E10. Compare the meter measurements with the slopes of your I vs . V graphs. (Remember: 1 ohm = 1 volt/1 ampere. Most of you plotted current in milliamps vs . voltage in volts. You must convert to amperes and realize the slope is 1/R, not R.) 2. Read the color code for all four of your resistors. Compare the manufacturer’s resistance value (from the color code) with your measurements. Are the resistors within tolerance?

    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.
