V = Vo(e^-t/RC)
770 = 910 (e^-t/(845*260*10^-6)
t = 0.036 s
so the time taken = 0.036s

A defibrillator delivers a jolt of electrical energy to restart a heart that is either stopped or undergoing ventricular defibrillation -- a rapid irregular beating. This energy is supplied by a charged capacitor. Consider a 265 μF capacitor charged to 2270 V in a defibrillator. A 4000 V power supply is used to charge the capacitor through a 36.7 kΩ resistor. If the capacitor is initially uncharged, how much time does it take to charge the capacitor to 2270 V?
