Physics 2306 Laboratory Equipment List

Lab 5: Mapping Electric Equipotentials

Transition notes:

  1. Everything should be put away. The Black Banana Plug Cable from electrostatics belongs in the bag for that lab.

Notes and tests:

  1. Black cables: DMM2->AC->DMM1, A->DMM2
  2. Red cables: DMM2->AC->B
  3. Red probe: DMM1
  4. Level the trays with a bubble level.
  5. Last TA of the day should vacuum out each of the trays and set them where they can dry.
  6. Test by turning on the power supply and the two DMMs.   Adjust the power supply so DMM2 reads 4 V.  Touch electrode A with the voltage probe attached to DMM1, it should read 0 V, then touch the probe to electrode B, it should read 4 V.
  7. The most likely problem with this set up is improper wire connections.   The next is a failed power supply.
