Homework Help: Thevenin Equivalent in AC circuit

  1. Nov 19, 2008 #1
    Hi All,

    My name is Joaquim and I'm new in this forums. I am a Electronic Engineer student (1st Year).

    I have a question about a Thevenin equivalent circuit in AC.

    I need someone to tell me if I'm doing the right math in finding the thevenin equivalent (AB point):

    Please see the following circuit:


    I need to calculate the inductor reactance
    (Xl) = 2 * Pi * F * L
    The capacitor reactance
    (Xc) = 1 / ( 2 * Pi * F * C )

    And then I add R1 to L1 reactance and parallel with C1 reactance.
    Finally, the result added to R2.

    ((R1+XL1) // XC1)+R2 = RThevenin

    Are my calculations correct or I'm missing something?

    Thanks in advance
