The potential difference between points `A` and `B` adjoining figure is

Options

A. `(2)/(3) V`
B. `(8)/(9) V`
C. `(4)/(3) V`
D. `2 V`

Answer

C

Explanation

(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 `(2)/(3) V`, and potential difference between `A` and `B` is `(4)/(3) V`.
