capacitor discharge??? 1. The problem statement, all variables and given/known data A 1.4 uF capacitor, initially uncharged, is connected in series with a 10 k ohms resistor and a 6 V battery of negligible internal resistance. How long does it take the capacitor to reach 99% of its final charge? this is part b. i already found out part a which asked What is the charge on the capacitor after a very long time? answer to this part was 8.4 uC 2. Relevant equations for part b i think i will have to use the equation Q=Qf(1-e^(-t/T)) where t is time and T is the time constant defined by T= RC 3. The attempt at a solution i plugged in arbatrary values just to define my 99% i picked 5 but that should not matter 5=4.95(1-e^(-t/(10000*1.4e-6))) solve for t this will be in seconds i assume and my answer wants it displayed in ms i got an answer of around 32 ms but it says im wrong. any help would be great!!!
