1. The problem statement, all variables and given/known data 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 2. Relevant equations Q=CV(1-e^(-t/RC) 3. 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?
