Basic Idea:

• Measure the resistance of two resistors in series.

• 7

	What:	How Many:	Where:
	40 volt DC regulated power supply	1	Majors storeroom, shelf C2
	Digital Multimeter	2	Majors storeroom, locked in steel cabinet
	Two resistor's mounted on board (see sketch below)	1	non-Majors storeroom, shelf P3
	Wires – 24"	4 (2 red, 2 black)	Bewkes 231 (Phys 152 Lab)
	Wires – 12"	1 (red)	Bewkes 231 (Phys 152 Lab)
	Sticky Notes	2	Jeff will get from the office. One for each multimeter
Place two extra multimeters on the instructor's bench (for spares)
	Digital Multimeter	2	Majors storeroom, locked in steel cabinet

Notes:

• Lab setup (photo details):
  • Place circuit boards following letter pattern below; place all setups so that students are facing the blackboard as shown below
  • Check with Jeff about which power supplies to use. Ideally they all should be the same (as shown in the photos), and the ones that students will use for the lab practical
  • The board used contains two resistors (~3kΩ) in series (shown at right)
  • Jeff will label all meters with sticky notes marked with V and A
