Q. The potential difference between points $A$ and $B$ of adjoining figure is
A) $\frac{2}{3}V$
B) $\frac{8}{9}V$
C) $\frac{4}{3}V$
D) $2V$
Explanation
(c) The given circuit can be redrawn as follows
For identical resistance, 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 $\frac{4}{3}V$
