How to find the thevenin equivalent in this circuit?

I'm having troubles with finding the thevenin equivalent in general, particuliary in this circuit: simulate this circuit – Schematic created using CircuitLab

My question is: how to find the thevenin equivalent considering the load is the one between point A and B?.

Please explain in detail the part of finding Rth. also i would appreciate a method, advice... which would help me to find the Rth in other circuit.

What i have tried: I calculated the Eth by making the load as an open circuit as shown and calculated the current in each branch then i applied the mesh law (KVL) in one of the meshs containing my load which gave me Eth=0.1486Volt. if it's wrong so how to find Eth. If possible, tell some hints before giving the answer.

Any help would be appreciated, thanks in advance.

• There are 210 questions on Thevenin theorem on this website plus huge huge resources, worked examples, etc. available online. Tell me why they didn't help you figure out your problem. – dirac16 Oct 13 '17 at 10:45
• @dirac16 have read many of them but that doesn't necessarily mean that i would be able to solve this one (they are in genral very different than this case). Anyway i have found your comment helpful, maybe looking for more examples will help. – Mehdi Oct 13 '17 at 11:04
