<img class="img-fluid question-image" alt="Solution" src="https://cdn.tardigrade.in/q/nta/p-fu9qtfwnykskh29m.jpg" /> Reff=(4/5)+(6/5)=2 Ω i=(20/2)=10A I=(4 i/5)-(3 i/5)=+(i/5)=2 A

Q. In the given circuit diagram, a connecting wire of negligible resistance is joining the points $B$ and $D$ , the current in the connecting wire is

zero

$2 A$

$0.4 A$

$4 A$

$R_{e ff} = \frac{4}{5} + \frac{6}{5} = 2 Ω$
$i = \frac{20}{2} = 10 A$
$I = \frac{4 i}{5} - \frac{3 i}{5} = + \frac{i}{5} = 2 A$
