Apply the laws in Fig. Q2 to find current through each branch.

To solve this problem using the Superposition Theorem, we will consider the effect of each independent voltage source separately and then sum the results.

Let's define the branch currents:

• $I_1$: Current through the 2 $\Omega$ resistor and 16 V source (left branch), assumed direction downwards.
• $I_2$: Current through the 3 $\Omega$ resistor and 9 V source (middle branch), assumed direction downwards.
• $I_3$: Current through the 6 $\Omega$ resistor (right branch), assumed direction downwards.

Part (i): Current in each branch

Case 1: 16 V source acting alone (9 V source replaced by a short circuit)

When the 9
