Basic Idea:

• Examine effects of voltage and current for parallel and series circuits. Also, examine open and short circuits.

• 7

Equipment Needed (each setup):

	What:	How Many:	Where:
New this week:
	Single pole knife switch	1	non-Majors storeroom, shelf P3
	Wire – 12" (7 wires total each setup needed this week; need to add 2 more 12" wires this week)	2 (red or black)	Bewkes 231 (Phys 152 Lab)
	1.5 kΩ resistor, mounted on white base (Labeled R1)	1	non-Majors storeroom, shelf P3
