By perpendicular axis symmetry all points 1,2,3 are at same potential, therefore junction on this line can be redrawn as RA B=(22/35) R <img class="img-fluid question-image" alt="image" src="https://cdn.tardigrade.in/img/question/physics/b163100350706edb72ae7ff159328bd3-.png" />

Q. Find the equivalent resistance of the circuit between points $A$ and $B$ shown in figure (each branch is of resistance $= 1Ω)$

$\frac{22}{25} Ω$ .

$\frac{12}{25} Ω$

$\frac{22}{35} Ω$

$\frac{12}{35} Ω$

By perpendicular axis symmetry all points $1, 2, 3$ are at same potential, therefore junction on this line can be redrawn as $R_{A B} = \frac{22}{35} R$
