Discharging capacitors?
I have a discharging capacitor connected to 2 power rails (6V and 0V) The capacitor has a value of 100 micro farads and the resistor in parallel with is has a value of 1.3 mega ohms (so a time constant of 130 seconds.) The question is calculate the time at which Vout=3v (assuming discharging begins at time=0)
I got an answer of 90.1 but I'm not sure if its correct? I'm kinda going from memory for the equations you see
thanks in advance

thanks in advanceThat's the correct answer.
t1/2 = CR Ln 2
Obtained from exponential decay formula after taking logs.
