i asked to find What should be connected instead of R6 to get the Maximum Electric power. so what i think i need to do first is to find RTh (R-Thévenin). so in the picture you can see the same Electric circuit (NO1 is the original Electric circuit,and NO2 is what i started to do to find RTH) but what i should do with the current source? (do i need to cut it?) i not sure if Thévenin's theorem is the correct way to solve this kind of question. need some help here. thanks.
