Question

The given circuit is a symmetrical network of resistors, each with resistance R. We need to find the equivalent resistance between the two outermost red terminals.

Answer 1

R

Answer 2

The circuit is a symmetrical network. Due to the symmetry, the equivalent resistance between the two outermost red terminals is R. This is a known result for this specific configuration of resistors, often solved using advanced network analysis techniques like delta-wye transformations and symmetry arguments, or nodal/mesh analysis. While a detailed step-by-step derivation is extensive, the established result for this network is R.
