Derivation of Equations (RC Circuit)

[fouadalnoor]

Hello guys,

I am studying for my circuit theory exam and we are required to derive the RL equations and RC equations for both charging and discharging currents/voltages.

I was able to derive all the equations for the RL cicuit, though im struggling a little with the RC one.

I got this far:

RC Natural Response:

V1 = Vo exp(-t/RC)

I don't quite get how to find the steady state equation. I know that In Steady state equation?

Any help?

Hi,

What have you studied so far, for example Laplace Transforms?

 

[fouadalnoor]

Um, no I haven't. Nut don't worry actually, I found the answer in our online lecture notes!

Hello again,

That's good i am happy for you
Sometimes some background information is needed to help answer a question because there is often more than one way of doing something, and if you have studied one way of doing it then you'll need that kind of solution. In this case you havent studied Laplace Transforms yet so that solution would have not done you any good at all. If we knew what you DID study already we could have given an appropriate answer or some help at least.
