<img class="img-fluid question-image" alt="Solution" src="https://cdn.tardigrade.in/q/nta/p-9jybbowp5dcm.png" /> Applying Kirchhoff's voltage law, I(2 + 8)=6+4 I.10=10 I=1 A VA-(I × 2)+6=VB VA-VB=(1 × 2)-6 And VB A=4 V

Q. The potential difference between $A$ and $B$ in the following circuit is

$4 V$

$5.6 V$

$2.8 V$

$6 V$

Applying Kirchhoff's voltage law,
$I (2 + 8) = 6 + 4$
$I .10 = 10$
$I = 1 A$
$V_{A} - (I \times 2) + 6 = V_{B}$
$V_{A} - V_{B} = (1 \times 2) - 6$
And $V_{B A} = 4 V$

Q. The potential difference between A and B in the following circuit is

4V

5.6V

2.8V

6V
