Question

The potential difference between points A and B in the given figure is?

Answer 1

Step 1: Given

Total Current, $I=2A$

Step 2: To find

The potential difference between points A and B.

Step 3: Calculation

Applying Kirchhoff's Voltage Law from A to B

$$\begin{gathered} V_A-2I-3-11-V_B=0 \\ \Rightarrow V_A-2\left(2\right)-3-1\left(2\right)-V_B=0 \\ \Rightarrow V_A-4-3-2-V_B=0 \\ \Rightarrow V_A-9-V_B=0 \\ \Rightarrow V_A-V_B=9V \end{gathered}$$

Hence, the potential difference between V_A and V_B is 9V.
