The figure can be redrawn as <img class="img-fluid question-image" alt="image" src="https://cdn.tardigrade.in/img/question/physics/c4a02750b32a3c87203ddfa61ef35b2c-.png" /> There will be no current through I and II. So III, IV and V will be in series. I=(6/3 R)=(6/3 × 5)=0.4 A

Q. A prism is made of wire mesh with each side having equal resistance $R$ . A battery of $6 V$ and zero internal resistance is connected across $E$ and $F$ as shown in the figure. The current in the branch $A D$ , if $R$ is equal to $5 Ω$ , is.

0.6 A

0.8 A

0.4 A

2 A

There will be no current through I and II.
So III, IV and V will be in series.
$I = \frac{6}{3 R} = \frac{6}{3 \times 5} = 0.4 A$
