Basic Idea:

• Check a resistor, incandescent bulb, and LED for compliance with Ohm's law.

	What:	How Many:	Where:
	40 volt DC regulated power supply	1	Majors storeroom, shelf C2
	Digital multimeter	2	Majors storeroom, locked in steel cabinet
	Black box with resistor & LED	1	non-Majors storeroom, shelf P3
	Small DC bulb (7.5 v, 0.22 A)	1	non-Majors storeroom, shelf L2
	Small DC bulb holder with Alligator clips	1	non-Majors storeroom, shelf L2
	Wire – 24"	4 (2 red, 2 black)	Bewkes 231 (Phys 152 Lab)
	Wire – 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 small bench by the sink (for spares)
	Digital Multimeter	2	Majors storeroom, locked in steel cabinet

Notes:

• Lab setup (photo details):
  • Place circuit boards following letter pattern below
  • Screw bulbs into sockets and attach alligator clips; leave all other components for students to assemble.
  • Jeff will label sticky notes with V and A, attach to each meter. Put a small Ω on the voltmeter sticky
