EM 101: OHM'S LAw

NOTE: Current is proportional to the number of batteries driving the circuit. This can be shown in 30 seconds, and is very effective. Simultaneous measures of I and (projection meter) V are possible, but take more lecture time. The 1-ohm resistor is accurate, and shunts are accurate if tightly fastened. Ask for help on this one -- many variations, some equipment limitations. Use only "Hobby Batteries" in good condition.

Equipment: Meter in cabinet 11, Batteries in cabinet 1, shelf G.
