A 30.0 μF capacitor initially charged to 20.0 μC is discharged through a 2.60 kΩ resistor. How long does it take to reduce the capacitor's charge to 10.0 μC ?
R = 2.6 kohms, C = 30 uF, Q = 10 uC, Qo = 20 uC
For a RC discharging circuit
Q = Qo (e^-t/RC)
10 = 20(e^(-t/(30*10^-6*2.6*1000)))
t =0.054 s = 54 ms
