Homework Help: Forced Response for RC cct.

  1. Feb 11, 2013 #1
    1. The problem statement, all variables and given/known data

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

    2. Relevant equations

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

    we start from :

    Vm cos (ωt) = Ri + L


    i = Im 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?
