The voltage on a charged capacitor is monitored with a voltmeter whose resistance is $1.00 \mathrm{M} \Omega .$ The table below gives the meter reading as a function of time. Determine a function of the voltage which, when you plot it against time, should give a straight line. Make your plot, establish a best-fit line, and use it to determine the capacitance.$$\begin{array}{|l|c|c|c|c|c|}\hline \text { Time (s) } & 0 & 1 & 2 & 3 & 4 \\\hline \text { Voltage (V) } & 15.0 & 10.3 & 6.36 & 3.78 & 2.43 \\\hline\end{array}$$
