In the circuit shown in figure ,
a. find the current is each branch
b. find the potential difference `V_(ab)` of point a relative to point b.

Explanation

To solve the problem step-by-step, we will first find the current in each branch of the circuit and then calculate the potential difference \( V_{ab} \) between points A and B.

### Step 1: Identify the Circuit Components
- We have two batteries: a 10V battery and a 5V battery.
- The resistances are:
- \( R_1 = 2 \, \Omega \)
- \( R_2 = 3 \, \Omega \)
- \( R_3 = 1 \, \Omega \)
