Useless wire!

Electricity and Magnetism Level 2

I had a useless metallic wire with a total resistance of $36 \Omega$ . I cut it into six equal pieces and formed a regular tetrahedron. What is the equivalent resistance between any two adjacent nodes in $\Omega$ ?

This problem is original.

This question is part of the set Platonic Electricity .

The answer is 3.

Here $r= 6 \Omega$ .

Here, I have used the method of equipotential reduction. The resistor between nodes $C$ and $D$ can be neglected.

Very nice :). Try this . Same method has to be applied but configuration has changed.
