Here's the solution for the circuit problem: Step 1: Define node voltages and apply Kirchhoff's Current Law (KCL). Let the potential at node N be V_N = 0 \, V (ground). Let the potential at node M be V_M. We will define currents flowing out of node M as positive. The central branch contains a 4 resistor, a 1 V battery (with 2 internal resistance). The total resistance in this branch is 4 \, + 2 \, = 6 \, . The 1 V battery's positive terminal is towards N, so it opposes current flowing from M to N. The current I_A
