    Hi all,

    I know that the forced response in RL cct. is :
    i = \frac{Vm}{\sqrt{R^2+(ωl)^2}} cos (ωt - tan^-1 \frac{wωl}{R}

    we start from :

    Vm cos (ωt) = Ri + L\frac{di}{dt}

    and

    i = Im cos (ωt-θ)

    -----------------------------------------

    but my question is :
    what is the forced response for Rc cct. and how to derive it??

    help please!
