Homework Equations
The Attempt at a Solution
I am trying to compute ##I_N##.
I connected nodes a and b. The circuit after some simplification:
$$\frac { 180-{ V }_{ 1 } }{ 20 } =\frac { 120-V_{ 1 } }{ 40 } \\ { V }_{ 1 }=240\quad V\\ \\ R=\frac { V }{ I } \\ 40=\frac { 120 }{ I_{ N } } \\ I_{ N }=3\quad A$$
The correct answer is 1A.
