Physics 2306 Laboratory Equipment List

Lab 7: DC Circuits 2

Transition notes:

  1. One current sensor from Lab 5 is put away and replaced by a voltage sensor.
  2. Remove the used batteries to the testing box, and put out 2 fresh ones for each board.
  3. Switch the components bags, making sure each bag is accurate.

Equipment List:

  1. 850 Interface with:
    • Current Sensors (Analog A) plugged in with:
      • 8 pin extension cable
    • 2 x Voltage Sensor (Analog B and C)
  2. Current limited Power Supply
  3. Multimeter With the following plugged into it:
    • Red DMM Probe
    • Black DMM Probe
  4. Circuit Board with the following on it:
    • 2 x D cell Battery
    • 3 x 2.25V light bulb (#222)
  5. Telegraph Switch (AKA telegraph Switch)
  6. 5 x 10cm Jumper Wire
  7. 5 x 25cm Jumper Wire
  8. Lab 6 Component bag:
    • 2 x 330 Ohm Resistor
    • 2 x 560 Ohm Resistor
    • 2 x 1 kOhm Resistor
    • 2 x Green LED
  9. Cables:
    • 3 x Red Alligator Cord (2 plugged into Current Sensors)
    • 3 x Black Alligator Cord (2 plugged into Current Sensors)
    • 4 x Red Alligator Clip (all but 1 attached to banana plugs)
    • 4 x Black Alligator Clip (all but 1 attached to banana plugs)

Notes and tests:

  1. Put alligator clip adapters on: both voltage probes, banana plugs coming out of the current sensor with alligator clip adapters on the end.
  2. Test all batteries to pass at least at the 80% level on the battery tester.
  3. Plug the remaining set of banana plug cables into the DC power supply and set it on the lab table.
  4. The current limit knob should be set to 9 o’clock position.
  5. Place the power supplies on the table. Test the power supplies with multimeter, and then turn the voltage to zero.
  6. Test the voltage sensors and current sensor with the test file "2306 Lab 6 test.cap" by setting up a simple circuit with the batteries and a bulb.
  7. Make sure that there is a supply of components in the TA cabinet.
