Question

Like explained in the experiment, suppose you first charge the capacitors in your RC circuit until the potential difference on the capacitor saturates at some initial value supplied by the power supply. Then you start to discharge your capacitor and read the potential difference on the capacitor in at different times. When you plot your data as lnV versus time, you make a linear fit which looks like the one on page 5 of your lab sheet.

If the slope points for this best fit line would be (10.7;0.736) and (21.2;0.437), calculate the time constant of this circuit experimentally. Give your answer in units of seconds with the correct number of significant figures.
