Question

The potential difference between the points $A$ and $B$ in the adjoining circuit diagram will be

• A. $\frac{2}{3}volt$
• B. $\frac{8}{9}volt$
• C. $\frac{4}{3}volt$
• D. $2\, volt$

Answer 1

Answer: (C)

$\frac{4}{3}volt$

Answer 2

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.
