Well I am once again at a stand still. Its basically a simple circuit problem, but not so simple to me. Heres where im at:

e^(t/RC) q = CV e^(t/RC) + K

All letters in capital are constant. So what i need to do from here is show that if q(0) = 0, then K = -CV.

It is probably easy but im new to the natural base honestly so if someone could explain the process a little bit, id really appreciate it.

This is the 1st of 2 parts

Thanks guys

Chris
