Analyze the given circuit. Assume the potential at node N is 0V. Calculate the potential at node M (V_M).

Okay, C, let's tackle these questions.

First, let's complete the previous question (Question 3) which was cut off. Assuming the question asks for the potential at node M ($V_M$).

Question 3: Circuit Analysis

Let's assume the potential at node N (bottom wire) is $0 \, \text{V}$ (ground). We will apply Kirchhoff's Current Law (KCL) at node M. Let currents flowing out of node M be positive.

• Left Branch: Contains a $1 \, \Omega$ resistor and a $9 \, \text{V}$ battery. The positive terminal of the $9 \, \text{V}$ battery is towards node M. The current $I_1$
