Data Analysis: Grab a copy of your graph for your lab report. To do this, click on the graph (it will get surrounded by a light blue rectangle). Then, you can copy-and-paste the graph into your lab report. Interpret the curve fit parameters. The functional form programmed into Capstone is: / V V0 e^(−t ≈ τ) should be the initial voltage. It might not be the Signal Generator voltage, because the V0 capacitor’s voltage decreased a little before you started recording data. is the RC time constant. τ Record your results in something like Table 2.1.
