\question \includegraphics[width=0.16\textwidth]{RC-switch.png}In the circuit shown the voltage across the capaciator is zero at time t=0 when a switch is closed putting the capacitor into contact with a power supply of  327\,V.  If the combined external and internal resistance is 204\,\textOmega\ and the capacitance is  68\,mF, how long will it take for the capacitor's voltage to reach 218.0\,V?
