At a recent exam I had this very simple problem concerning Kirchhoffs Laws:
I am concerned with problem c
Now my understanding of this is:
I can combine both nodes, and since all currents in the node need to cancel out, \$i_c\$ should be 2A. Now my professor marked this problem as wrong and told me it should be 8A instead.
Am I doing something fundamentally wrong here?
Update: The professor reviewed the answer sheet because some other answers were wrong and did not mention the 8A again, and accepted the solution 🤷♂️
