Q.
The potential difference between $A$ and $B$ in the following figure is
NTA AbhyasNTA Abhyas 2022Current Electricity
Solution:
According to Kirchoff's voltage law to the given branch,
Potential difference to the resistance is given by, $V=iR$ , where $i\&R$ represents current and resistance.
$V_{A} \, -2 \, \times \, 6- \, 12- \, 2 \, \times \, 9+4- \, 2 \, \times \, 5=V_{B}$
$\therefore \, V_{A}- \, V_{B}=48 \, V$
