Can anyone give me an idea of how to solve this problem? Do I want to convert the current sources to voltage sources or visa-versa? I was thinking of making the 2A and 4A current sources into voltage sources by V = IR. So (2A)(10Ω) = 20V and (4A)(12Ω) = 50V ? Then I was thinking of using mesh analysis to find the current in each loop. P = (I^2)(R) is what I believe I will use to solve. Please help with any explanations on what I need to do to solve this problem would be greatly appreciated!
