I have been out of school for almost 4 years and I realized the hard way that I am a little bit Rusty on these.
I think I was able to solve #1 by redrawing the circuit and using a common method that is used to solve a typical wheatstone Bridge Circuit.
For #2 I am really having a hard time to redraw the circuit. I am not sure if I should draw a wire from V1 directly to the ground and then apply nodal analysis or if I should use another method that I am not aware of. I tried that and I ended up with 2 unknown and 1 equation.
I am also not sure that to interpret circuit diagrams where some nodes are just left hanging in the air like V1 in problem #2, and #3.
I totally have no idea where to start on #3 and on #4 so please help me understand these Circuits.
I really appreciate your help.
Thank you very much
