Homework Statement
How much time does an RC circuit require to become fully charged assuming that the capacitor was initially uncharged.
resistance = R
capacitance = C
Voltage = V
Homework Equations
Q=CV(1-e^(-t/RC)
The Attempt at a Solution
so T = -ln(Q/(CV) - 1)RC
but Q = 0 since it's initially uncharged?
so T=-ln(0-1)RC
I'm not quite sure what to do for this problem because this error isn't in the domain of the natural log. Honestly, I don't even understand the formula, if CV is the final possible charge, then is Q=CV?
