Voltage (V) Time (s)
1.2790 0.01624
2.6000 0.03791
3.9210 0.06844
5.1790 0.11801
The final voltage the capacitor reaches after you go get somecoffee is 6.500 V.
(i) Enter the above data into an Excel spreadsheet.
(ii) Perform all calculations needed to compute -ln[(Vfinal -V)/Vfinal] for each voltage in this question.
(iii) Make a plot -ln[(Vfinal - V)/Vfinal] versus the time.
(iv) Use the trendline option in Excel to fit the data of-ln[(Vfinal - V)/Vfinal] versus the time to get the slope.
(b) Report this value below.
Slope = ?
(c) Determine the time constant from the slope.
t = ?
