A 500 micro-Farad capacitor is charged to an initial voltage of 10 V. It is then allowed to discharge through a 40 k0 resistor. You take measurements of voltage versus time and record a voltage of .80 volts after 50 seconds, and a voltage reading of .47 volts after 60 seconds. What is your percent error against the theoretical value of the voltage reading after three time constants?
