Click For Summary
The discussion focuses on deriving the forced response for an RC circuit, specifically seeking clarity on how to approach the problem. The initial inquiry references equations related to RL circuits, indicating confusion about applying similar principles to RC circuits. Participants emphasize the need to clarify whether the goal is to solve a differential equation for current or to find the steady-state AC response. The conversation highlights the importance of understanding the voltage across the capacitor in the context of the forced response. Clear guidance on these points is essential for solving the problem effectively.

Homework Statement



what is the forced response for Rc cct. and how to derive it??

Homework Equations



I know that the forced response in RL cct. is :
i = cos (ωt - tan^-1

we start from :

Vm cos (ωt) = Ri + L

and

i = I am cos (ωt-θ)

Can anyone help please!

just give me the voltage of capacitor law.
I don't know how to start,
 
It's not clear from your description what it is you're trying to do. Are you trying to write and solve the differential equation for the current in a series RC circuit? Or do you just want the steady-state AC response (AC current given the AC driving voltage)? Something else?
