Hello guys,,,,,,,, I've an assignment for electronics that i should deliver on Saturday but there is a problem that i can't solve anymore so pllz help me !!!???
in this pic he wants R Thevenin pllz tell me how to find it while having 2 sources one is voltage and the other is current and u can't use source transformation !!!

To find Rth all you need to do is to replace all voltage sources with short circuit and all current sources with open circuit.

i mean that if he wants me to put this circuit in the Thevenin form (A voltage source(Vth) and A resistance(Rth)) in series.
now we have Rth=6 Ω
we have to evaluate Vth ...how could we do this??
hint:i mean that i want the Thevenin equivalent circuit for it :):)

OK. I understand now. Simply use circuit analysis to find Vth.
For example try use superposition
And yes Rth resistance is equal to = 2 + 12/3 = 6Ω

You don't need to be sorry. Did you managed to solve this problem and find the answer?
I find Vth = 52V and I use superposition.
First I remove a current source (open circuit) and find Vth1. Next I remove a voltage sources (short circuit) and connect a current source and find Vth2. And finally answer is Vth = Vth1+Vth2
