Question

In the adjoining figure the potential difference between the points $A$ and $B$ will be -

• A. $\frac{10}{3}V$
• B. $\frac{4}{3}V$
• C. $\frac{8}{9}V$
• D. $\frac{2}{3}V$

Answer 1

Answer: (A)

If $I$ is current through $ABC$
$I=\frac{5}{21},V_{AB}=I\times (7+7)$
$V_{AB}=\frac{5}{21}\times 14=\frac{10}{3}$ Volt
