    Here's a problem my professor gave us to study and I need help figuring out the equivalent resistance of this schematic in order fully analyze I0. I believe the first step to get 13/3mA for I0 is finding Req. What I did was take the 3k parallel to the 6k whose equivalent resistance is in series with the 2k. The equivalent resistance of those 3 resistors are then parallel to the 4k. My final equivalent resistances is 2k, but when I find the I0 using simple KCL and KVL I get 4mA instead of 13/3mA.
