Hello Everyone,
I need to solve this problem:
How many seconds does it take to charge a 7.7 x 10-7 farad capacitor to 70V if it is initially uncharged, then connected to a 190V battery through a 11000 ohm resistor.
What I have so far:
q = CV
q = (7.7 x 10-7f)(70V)
q = 5.39 x 10-5C
q = q0e-t/RC
5.39 x 10-5 = q0e-t/(11000)(7.7 x 10-7)
What is q0 here?
