I have a certain circuit in mind and I want to find its Thevenin equivalent resistor:
I see that there is an dependent voltage source so I add a voltage source of 1V between a and b and make the other voltage source equal to 0 (the independent 9v). when I use nodal analysis on the new circuit, I am not sure how to calculate the current i3. I thought about using Kirchhoff voltage law on the middle loop but for now I am confused. If I have three voltage sources, do I just take a wild guess about which way the current goes when I apply KVL on the middle loop? because if they didn't note the direction of the current on the Vx resistor, I would have said that Vx+2i3-2Vx+1=0, or would that be wrong because I assumed i3's direction to go to the right?
- how would I do a KVL equation on the middle loop
- is there an easier way to solve it using nodal analysis (specifically, to find i3)?
Sorry if the question seems a bit confused, because I'm confused.
