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

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 $\frac{4}{3}\,V.$
