Question

The potential difference between points A and B of adjoining figure is -

• A. 2/3 V
• B. 8/9 V
• C. 4/3 V
• D. 2 V

Answer 1

The correct option is C 4/3 V

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