Homework Help: Thevenin equivalent circuit

  1. Nov 22, 2011 #1
    Here the attachment is the question.

    I have some experience in solving Thevenin with Voltage source, but not with current source.
    Any idea?

    thanks and regards,

    You will want to find the voltage across the terminals, which would merely be the voltage across the [tex]5I_x[/tex] element.

    Nodal analysis looks promising.

    If you slap a load impedance ZL onto the output and can wrestle the output node voltage expression into the form:
    [tex] Vo = V_{th} \frac{Z_L}{Z_L + Z_{th}} [/tex]
    then you're golden. It may take some creative grouping of terms to isolate the Vth and Zth bits :smile:
