Lab 2 - Introduction to resistors, breadboard and multimeters

To do this lab you will need: the breadboard, multimeter, 3 resistors and a 9 v battery with its clips

  1. Get your multimeter and two probes.
  2. Turn the multimeter on and switch the dial to the “Ohm” range.
  3. Now verify basic function by gently touching the probes together.
  4. Comment on what happens
  5. Using your fingers (see Figure), hold one of the meter probes to each end of the resistor.
  6. What do you record?
  7. Using one of the resistor color code chart (four bands and five bands) following compare the value of what you measured with the multimeter and the color code chart. (Note that then second chart really combines both types of resistors.)
  8. Are your measurements within the calculated tolerance?
  1. Build a parallel circuit, per diagram below.
  2. Without using the multimeter calculate What should the resistance between A and B be?
  3. Verify this via multimeter measurement. What do you record?
  4. Snap a photo.
  5. Now connect a 9V battery per circuit below. Without using your multimeter calculate how much current should now flow through R 1?
  6. Measure the current through R 1.
  7. Measure the current through the other two resistors
  8. Sum up the current and comment on the result.
  9. Snap a photo.
  10. Let’s built the following circuit.
  11. Repeat steps 21 through 23.
  12. Now connect a battery and repeat steps 2 7 through 31
