## Main Question or Discussion Point

Hi, I have a simple question: if I have a circuit with a capacitor, how do I calculate the voltage on the capacitor in function of time, I mean I know that tau(τ)=RC and there is the general formula X(t)=X(0)+[X(0)-X(∞)]

^{-t/τ}. So here comes my question should I consider the capacitor as the load and calculate the Thevenin equivalent voltage at t=0 and t=∞ and use the X(t)=X(0)+[X(0)-X(∞)]^{-t/τ}forumla ,where τ=R_{Th}C.
