hi i have a question i need to work out theoretical calculations using thevenin's theorem, nortons theorem and maximum power theorem. for this circuit which has multiple resistors and 2 power sources but i don't know how to do it. i did the practical test results in college but i have no notes on how to do it theoretically. is it possible for someone to explain how i do this for all 3 theorems in a step by step so i can understand. thanks mike

circuit is attached to this post
