MCQ
The potential difference between points $A$ and $B$ of adjoining figure is
- A$\frac{2}{3}\,V$
- B$\frac{8}{9}\,V$
- ✓$\frac{4}{3}\,V$
- D$2\,V$
✓
Answer
Correct option: C.
$\frac{4}{3}\,V$
c
The given circuit can be redrawn as follows
The given circuit can be redrawn as follows
For identical resistances, potential difference distributes equally among all. Hence potential difference across each resistance is $\frac{2}{3}\,V,$ and potential difference between $A$ and $B$ is $\frac{4}{3}\,V.$
