# Thevenin's theorem

So I watched a couple videos on Youtube about Thevenin's theorem and I found 2 ways to do this circuit,but I get two different answers and I'm confused now.(for finding $$\V_{th}\$$) First method is

$$\V_{th} = (V_s/R_1+R_2)R_2\$$ and i get 24 V

The second method is using KCL so, $$\I_1-I_2+I_3=0\$$ and I get $$\V_{th}\$$ = 30V

are both ways right and I'm just calculating wrong or I can't use method 1 for this circuit. Can someone explain please. • They should definitely give you the same answer.

I recommend you use Thévenin's and Norton's theorem in each of the elements instead. Start from your circuit, and apply Norton to the 32V supply and the 4 Ohms resistors. simulate this circuit – Schematic created using CircuitLab

Then add the two current supplies and find the parallel equivalent of the 4 and 12 Ohms resistors (which is 3 Ohms). simulate this circuit

Now all you have to do is apply Thévenin again and you pretty much have your answer. simulate this circuit
