Extending the Model for Electric Current

PHY 100


Students combine what they learned about series and parallel circuits to further explore how circuits work.


Name Location Quantity
Holder, Light Bulb, Miniature JE-105A-S137 3 per table
Light Bulbs, Miniature #48 JE-105A-S137 8 per table
Wire, Copper, Insulated, #22 JE-105A-S137 9 per table
Switch, Electric JE-105A-S137 1 per table
Power Supply, Extech (Model #382213) JE-105A-X12/13 1 per table
Holder, light bulb, 5 soldered together JE-105A-S137 1 per table
Wire, Banana Patch Cords, Hookup Leads JE-Lab Rooms-ByChalkboard 2 per table


If power supplies aren't in 105A they may be on cart JE 105A-016 which is often left in room JE 109. Make sure power supplies are all turned off, the knobs are all turned counter-clockwise as far as they can and the switches on the sides are on V, not MA. The circuits of 5 bulb holders soldered together should be filled with bulbs. Place bulbs in the 3 loose holders as well. Blown bulbs have been finding their way back to the main supply of bulbs, so check all bulbs when setting up the lab.

Along with the initial apparatus set-up, supply a sufficient number of the appropriate paper procedure handouts for all of the lab sections that will use the set-up over the course of the week. Print the PDF, duplicate to double-sided pages, staple, and leave pile on instructor's table prior to first use of set-up.
