ECE 201L Circuit Analysis Laboratory
Lab 1

This lab provides experience with resistors and multimeter measurements.

  1. You were given two resistors at the start of the lab. When you are finished with them, tape them to your report before submitting the report.

    For each resistor

    1. Describe the color code
    2. Report the nominal value corresponding to the color code
    3. Report the measured resistance.
    4. Calculate the percentage difference between the measured and nominal resistance.

  2. Measure your resistors in series (end-to-end) and in parallel (side-by-side)

    Resistors in series
    Resistors in parallel

    Calculate the series and parallel resistance from the formulas above. Compare the results (percentage difference) to the measured values.

  3. Use the nominally identical resistors given to you by the lab assistant. Measure each resistance using the bench multimeter, enter the results into Excel. Determine the nominal resistance of the batch from the color code. For each measured value determine the percentage difference from the nominal value. Calculate the average, standard deviation, and median of the set of percentage differences.
