Experiment 2
Referring to Experiment 1, determine unknown resistance values. We will use three resistors,
each of which has four colored bands.
Resistor 1 (Brown, Green, Brown, Gold)
Analysis – Step 1
Input the data on your graphic calculator and graph it.
Analysis – Step 2
Use the graphic calculator to determine the slope of the line.
a = 6.81 10
–3
Analysis – Step 3
Determine the resistance value.
R = 147
Resistor 2 (Yellow, Violet, Brown, Gold)
Analysis – Step 1
Input the data on your graphic calculator and graph it.
Analysis – Step 2
Use the graphic calculator to determine the slope of the line.
a = 2.16 10
–3
Analysis – Step 3
Determine the resistance value.
R = 463
