Passage / Comprehension

Twelve wires of equal resistance R are placed in a given arrangement as shown in figure. Then find

Equivalent resistance between A & O is

Answer:

Solution:

With current in at A and out at O, the reflection symmetry about the line AOD makes (B, F) and (C, E) equipotential pairs.

Collapsing these pairs and reducing the network gives $R_{A O} = \frac{9 R}{20}$ .
