University of Nevada, Reno Electrical & Biomedical Engineering Department EE220L Circuits I Laboratory Lab. 2: Basic DC Circuits, Part I 1 O BJECTIVE This lab introduces the basic properties of resistors and resistor networks, along with serial and parallel equivalent circuits. Voltage and current dividers will also be explored. P ROCEDURE I. R ESISTANCE 1. Obtain resistors of values 1k Ω , 4.7k Ω , and 8.2k Ω . Use a resistor color code chart (one can be found in Appendix A) to verify their values. 2. Using a multimeter, record the resistance values of each resistor. Note : Do not touch the resistor leads with your hands when you are recording your measurements. If you do, your body resistance will likely affect your measurements, as you are putting your body resistance in parallel with the circuit. 3. Now, for all three resistors, determine the percentage difference between your measured value and the accepted value that is decoded using the resistor color code. 4. Is the percentage difference within the manufacturing (initial) tolerances indicated by the color code for each resistor? For example: My color code says I have a 1.5k Ω resistor with a tolerance of ± 5%, but when I measure the resistance of that resistor, I measure 1.550k Ω . This indicates that the resistor is 3.33% off from the rated value and within the ± 5% tolerance specified. But, if that original 1.5k Ω resistor had a color code indicating it was a ± 1% tolerance resistor, then the resistor would be out of tolerance. II. S ERIES R ESISTANCE Figure 1: Circuit 1 - Two Series Resistances 1. Build Circuit 1. With a multimeter, record the resistance of the circuit. 2. Calculate the series resistance mathematically using the series resistance equation: R Total = R 1 +R 2 +…+R N 3. How does the measured value compare to the calculated value? Hint: Utilize the percent difference equation.

    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.
