Data Collection
1.
Press
. The GLX is now measuring voltage, but it is not recording data.
2.
Connect the black lead of the voltage probe to the negative terminal of the
battery.
3.
Place the red lead of the probe in contact with the circuit at point A.
4.
Press
to record a single voltage measurement.
5.
The GLX will prompt you to enter r, the total resistance across which the
voltage is measured. (For point A, r = 0.) Type the value of r and press
.
6.
Repeat steps 3, 4, and 5 for points A through F.
7.
When you are finished recording data, press
.
Analysis
1.
Press
to automatically scale the Graph.
2.
Does your data appear to agree with your prediction?
3.
Apply a linear fit to the graph and find the slope.
a)
Press
to open the Tools menu; press
to select Linear Fit.
b)
What is the slope (including units) of the best-fit line?
slope = __________
c)
What physical quantity does the slope represent?
