1. The problem statement, all variables and given/known data

Hi everyone,

I'm new here. This is my first post. I found physicsforums when researching on google a solution for a doubt I've had when trying to solve rc step response. Basically, the RC analyse showed at http://freespace.virgin.net/ljmayes.mal/circuittheory/Rcstep.htm" solves step by step the mathematical behave of RC circuits.

I understand the whole anylise but the line with the follow part (integrating):

2. Relevant equations

[tex]\int[/tex]dt = RC[tex]\int[/tex][tex]\frac{1}{Vin - Vc}[/tex]dVc

t =-CR ln(Vin - Vc) + const

Thanks in advance
