    Finding the time in which a potential drop is equal to 3V

    RC is in s. So then it would just be 3=12e^(-t/7.21) t=10s

    Finding the time in which a potential drop is equal to 3V

    I went from 6=12e^-5(RC) ln(1/2)=-5/RC RC=7.21 Is that correct?

    Finding the time in which a potential drop is equal to 3V

    It would equal 5ln(2), but I don't know how to use that for the answer. If I plug it in, there are lots of natural logs.

    Finding the time in which a potential drop is equal to 3V

    Homework Statement Capacitor, C1, is initially charged so that it has a potential difference of 12V. At time t=0, switch S1 is closed allowing the capacitor to discharge through resistor R1. At t=5, the potential across the capacitor has fallen to 6V. At what time will the potential across the...
