Q. The potential difference between points $A$ and $B$ is

$\frac{20}{7} V$

$\frac{40}{7} V$

$\frac{10}{7} V$

$\frac{12}{7} V$

$I_{1} = \frac{10}{10} = 1 A$
$I_{2} = \frac{10}{7} A$
$K V L$ from $A$ to $B$
$V_{A} - 6 X I_{1} + 3 \times I_{2}$
$= V_{B}$
$V_{A} - 6 + \frac{30}{7}$
$= V_{B}$
$V_{A} - V_{B}$
$= \frac{42 - 30}{7}$
$= \frac{12 V}{7}$
