The circuit can be folded about B and redrawn as <img class="img-fluid question-image" alt="Solution" src="https://cdn.tardigrade.in/q/nta/p-gvckuzbhozyc.png" /> Hence equivalent resistance between A and B is 2R=2× 7Ω =14Ω .

Q. In the shown wireframe, each side of a square (the smallest square) has a resistance $7 Ω$ . What is the equivalent resistance value (in ohm) of the circuit between the points $A$ and $B$ ?

The circuit can be folded about $B$ and redrawn as

Hence equivalent resistance between $A$ and $B$ is $2 R = 2 \times 7Ω = 14Ω$ .
