BACKGROUND RESEARCH:<\/strong><\/u><\/p>\n

In preparation for the lab, research what resistance tolerance is and what causes is. \u00a0Think about the impact resistance tolerance would have on measured values in a circuit. \u00a0While resistance tolerance means that a given resistance will have a different resistance other than the ideal, it will not fluctuate over a short period of time. \u00a0Think about these questions before starting the lab as it will help you in the analysis: \u00a0Why then in a physical electrical circuit do the measurements fluctuate? \u00a0What are the other factors involved? \u00a0Is there anything else which effects the resistance value when placed in a circuit in a certain location?<\/p>\n

LAB:<\/strong><\/u><\/p>\n

This week\u2019s lab introduces you to the construction of a resistive network in Multisim and identifying the effect of tolerances. You will learn to utilize Multisim to confirm your calculations.<\/p>\n

    \n
  1. See the circuit below. For the load resistor of 7 K\u2126, use the tolerance levels in the table to calculate \u2018Vx\u2019 to fill in the \u2018Calculated Vx\u2019 in the table below. \u00a0When the tolerance is included in the calculation, the calculated Vx will be in the form x +\/- y. \u00a0(It should be noted that usually tolerance levels are not used in calculations. \u00a0Rather, an ideal circuit is assumed, and it is expected that the measurements will not be exact due to the component tolerances.) \u00a0Be sure to show your calculations, step by step (read rules above).<\/li>\n<\/ol>\n

    5%<\/p>\n

    7K\u2126<\/p>\n

    10%<\/p>\n

    2. \u00a0Construct the above circuit in Multisim. \u00a0If you need help with Multisim, refer to the tutorials in the Tools and Templates section. \u00a0Please use the following documentation<\/u><\/a> (also found in the Tools and Templates) if you need help setting up tolerances in Multisim. Use the Agilent Multimeter to make measurements.\u00a0<\/p>\n

    3. \u00a0Simulation:<\/p>\n

      \n
    1. Run simulation to measure the voltage drop across the 7K\u2126 resistor and record the measurements in the first box under \u2018Measured Vx\u2019 column. \u00a0Take a time-stamped screenshot of the result.<\/li>\n
    2. Now, add the tolerances to the resistor based on the tolerances in the table and run the simulation to complete the table. Run the simulation three times in order to obtain three measured values for each tolerance. \u00a0It is IMPORTANT<\/strong> to note that this variation in the simulation is NOT due to one resistor. In other words, it is as if the simulation takes out the resistor in the circuit, goes and gets another resistor out of the bin with the same tolerance, puts it in the circuit, and runs the simulation. \u00a0Take at least one time-stamped screen capture for each tolerance level.<\/li>\n<\/ol>\n

      4. \u00a0Analysis: \u00a0In this section, you are to analyze your results. \u00a0While the following questions MUST be answered, they may NOT be exhaustive nor represent all that you may want to look at. \u00a0You may have other items you would like to address or calculate. \u00a0You may have an idea to expand the table for the analysis to look at an additional item. \u00a0You are free and expected to do that here as this is a minimum guide.<\/p>\n

      a. \u00a0Calculate the average measured value for each tolerance level.<\/p>\n

        \n
      1. Do the measured values match the calculated values? If not, explain why they are different?<\/li>\n
      2. Explain the significance and the effect of adding resistor tolerances on your measurements of \u2018Vx\u2019 in Multisim?<\/li>\n
      3. Do the measured and average values seem reasonable in light of your calculated values? \u00a0What is the relationship between the measured values and your calculated value?<\/li>\n<\/ol>\n

        e. \u00a0While the simulation mimics changing out the resistor with a new resistor every time you run the simulation, it also reflects some of the variation one might experience with one resistor in a typical operating scenario. \u00a0Why is that? \u00a0What things besides tolerance effect the resistance value and measurements in real circuits? \u00a0Explain at least one of those items in detail from the perspective of physics.<\/p>\n

          \n
        1. Create your lab report in a word document called \u201cLab1_StudentID.docx\u201d with your GID substituted into the file name. \u00a0Refer to the submission rules above. Be sure to include calculations, your analysis and answers to questions, screenshots, summary, etc.\u00a0<\/li>\n
        2. Upload file \u201cLab1_StudentID\u201d.<\/li>\n<\/ol>\n

          2. \u00a0All screenshots must be included.<\/p>\n

          4. \u00a0Any and all Multisim files must be submitted.\u00a0<\/p>\n

          5. \u00a0Any equations used must be typed in Word.\u00a0\u00a0Copy and paste of equations from outside sources is prohibited.<\/u><\/p>\n

          6. \u00a0No graphics are allowed in the Word document other than screenshots of circuits from Multisim and hardware if applicable, with the date\/time stamp.<\/p>\n

          7. \u00a0The lab template should be used.\u00a0 Specifically, it is brought to your attention that a summary MUST be provided explaining the results of the labs, the relationship of the results to expected results, and any challenges encountered.<\/p>\n

          8. \u00a0Hardware portion of labs should include screenshots of the assembled circuit with your name and student GID number written on paper next to the circuit.\u00a0There should be screenshots of the instrument readings with the date and time stamp on lower right corner clearly shown.<\/u>\u00a0See example below.<\/p>\n
