Hello again!
I'm always getting stuck on problems where I have several current and/or voltage sources in various combinations. In both examples i'm supposed to create a Thevinin circuit but I can manage R_TH myself.
Example 1 shows how I normally assume currents go and attempting to calculate this will be wrong every time except when I assume that the two loops does not interact with eachother.
Example 2 is pretty much the same deal. If I assume that the entire circuit is made up by 3 closed circuits I get the right answer.
Can someone please explain why the current I does not stray from the closed loops despite it being connected to the other loops?
