DCS# 5F10.10
OHM'S LAW
APPARATUS
resistor
203
two DMMs
207
power supply
105-16-C
video camera
103
DESCRIPTION
Vary the power supply voltage to show that the current through the resistor is proportional to the voltage across it.
NOTES
Use a resistor value for which the calculations are easy to do in ones head, e.g. 2k ohm, 1/2 Watt.
