Hello, I have practice questions on Thevenin theorem. Where I seemed to have gotten stuck. With independent sources it's very simple to find the Thevenin equivalent circuit but this question throws one dependent source thus the steps change.
I know that to solve this, I have to:
1) Find Voc.. Which I did using nodal analysis
2) short circuit terminals a and b and then find In current passing through that short circuit
3) use Rth = Voc/In to find the Thevenin resistor
The problem arises when I short circuit the terminals. I tried using mesh analysis by putting 4 current loops but I ended up with a negative current, thus resulting in a negative Rth which isn't possible apparently.
I don't need anyone to do it for me. I just need some reassurance that i'm going in the right direction. Additionally, I also thought that when I short circuit a and b doesn't that break the whole circuit and render it useless? Anyway, would appreciate any thoughts.
