Thevenin's Theorem and Norton's Theorem

  • #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.)
