Thevenin's Theorem and Norton's Theorem

  1. Sep 22, 2010 #1
    Hi guys, I'm stuck with determining how will I solve this circuit using Thevenin's and Norton's Theorem.

    Given Problem: From the circuit (which is in the image), find the voltage across a 6-ohm resistor using Thevenin's Theorem and Norton's Theorem.

    The attempt at a solution

    Using KVL on the four loops, I will get:

    7Ia - 6Ib = 12 ---- Equation 1
    13Ib - 3Ic = 3 ---- Equation 2
    -15Ic + 7Id = 3 ---- Equation 3
    7Ic - 9Id = 9 ---- Equation 4

    and here I don't know what's next.

    Our professor gave this problem without teaching the principles of Thevenin and Norton's Theorem. So a short discussion while solving the problem is much appreciated. Thank you. ^^

    Start by reading your textbook about Thevenin and Norton equivalents. If you don't have a textbook, Wikipedia has a decent summary of them. Describe to us what the theorems say you can do. (Don't get too bogged down in how to find them. I just want you to get the idea of what you're trying to do.)
