Step-by-step solution

Using the principle of superposition, we analyse the circuit with one source active at a time. Case 1: Only the 10 V source is active (the 5 V source is replaced by a short circuit). With the 5 V source shorted, the top and bottom nodes of the bridge are directly connected by a wire, forming a Wheatstone bridge. Checking for balance: Left arm ratio: 4 4 = 1 Right arm ratio: 2 2 = 1 The ratios are equal, so the bridge is balanced. Hence, no current flows through the middle branch connecting the two nodes, and the co
