Physics 2216 Laboratory Equipment List

Lab 5: Forces Between Electric Charges

Image of the old set up, a red bin that held a small stand and what looks like trash

Don't you wish it was still this easy?

Equipment List:

  1. 850 Interface
    • USB - mini USB Cord
    • Power Cord
    • 850 Interface Power Supply
  2. Aluminum Pan
  3. Electrostatics Cable Bag
    • BNC to Alligator Cord Electrostatics type
    • Banana Plug Cord - Black
    • Banana to Spade Cord - Black
    • Banana to Spade Cord - Red
    • 8 pin DIN to Mini - DIN cord
  4. 2 x Lid as Electrophorus (Tray Lid)
  5. Electrometer
  6. 4 x AA Batteries
  7. Faraday Ice Pail
  8. Electrostatic Power Supply
  9. Electrostatic Power Supply AC Adapter (Please note that there are two types and they are all compatible with one another.)
  10. Electroscope
    • Small Electroscope Plate with Plug
    • Electroscope Ball with Plug
  11. Electroscope Condenser Wand
    • Large Wand Plate (attached)
    • Small Wand Plate (loose)
    • 2 x Charge Wand Screw
    • 2 x Charge Wand Plastic Washer
  12. PASCO Proof Plane
  13. 1 pair Insulating Gloves(To be replaced by S26)
  14. 3 x Aluminum Ball Bearings in Bags
  15. Bearing Tweezers
  16. 2 x Lid Electrophorus
  17. Microfiber Cloth

General Class Use :

  1. Place a stack of Microfiber Cloths at each TA table.
  2. Make sure there is a Laundry Bag for each quad.
  3. Isopropyl Alcohol
  4. Box of Kim Wipes

Notes and tests:

  1. Clean the plastic parts of wands, electroscopes,lids, and proof planes with kim wipes and alcohol. Be sure to wear gloves and other PPE
  2. Follow This Guide to hook up the electrometer and ice pail.
  3. Load the 2306 test file“2306 Lab 3 test.cap” and click “start”.
  4. Set the electrometer to the 100 V scale and turn it on.   A green indicator light should display on the front panel.   If the green indicator light is blinking the batteries need to be replaced.  The batteries are easily knocked out of their holder. If the electrometer doesn’t work check to see that they are installed properly.
  5. Touch a lead connected to the 30 V output of the voltage source to the in cylinder of the Ice Pail and check to see if the electrometer reads about 30 V. Then touch the ground spade to the same cylinder to dissipate the charge.

It's a lot...

Additional Images below:

The fur and wands used to create and hold charge all set up neatly on top of the lid

Neatly store what you can on top of the lid.

The Electroscope with the plate plugged into the top and the sphere in the bottom

The electroscope should look like this when put out.

Faraday Ice Pail and Electrometer Set up Instructions Below:

Ice Pail wiring and set up. Note that the black clip goes on the outside and the red clip foes on the inside.

Wires connected to the Electrometer

The Electrometer has 3 wires plugged into it:

  1. The 8 pin DIN to smaller 8 pin wire is plugged into the singal output socket on the left side.
    • The other end of this wire is plugged into Analog A of the interface.
  2. The BNC to alligator wire is plugged into the Coaxial BNC jack on the right side.
    • The other end of this wire is clipped onto the Ice Pail
  3. The black banana to banana wire is plugged into the ground socket on the right side.
    • The other end of this wire is plugged into the com socket of the power source.

The Power Source must be turned on with the switch in the back to work.
