I don't have any question in particular, the source of my confusion is more conceptual.
First lets consider a regular RC circuit with a switch that asks us to find, say Vc(t) for t>0 (Let's assume the switch will close or open at t=0)
So I can find Vc(0-) (i.e. the time interval right before 0).
After this I'm going to attempt to find Vc(t) for the interval t>0.
Now here is where I get confused:
When do I know if I can apply the following equation,
\(v_{c}(t) = v_{c}(\infty) + ( v_{c}(0) - v_{c}(\infty))e^{\frac{-t}{\tau}}\)
?
In other words, in what cases can I not use the following equation?
Can I use this equation when dealing with a unit step source?
