You measure the potential difference across a capacitor atdifferenttimes while it's charging and record the followingresults:
Voltage (V) Time (s) 1.229 0.01651 2.479 0.03810 3.771 0.06966 4.979 0.12016
The final voltage the capacitor reaches after you go get somecoffeeis 6.250 V.
(a) Use Excel to construct a spreadsheetthatshows
(i) the above data as well as any andallcalculations needed to compute the resistance of thecircuitcomponent in question;
(ii) create a graph of-ln[(Vfinal-V)/Vfinal]vs. the time;
(iii) use Excel's trendline to plot a best-fit line through thedataand determine the slope from it.
(b) What is the slope of your graph?
Slope = 1
Time Constant (RC) =
