to find equivalent resistance between
1) adjacent pt's of a face
2) diagonal opposite pt. on a face
3) diametrically opposite corner.
given each side has resistance r.

i made all these by considering symmetry & finding pt.s having same potential & then simplifying the circuit. i got the answers, but my method is typically lenghty. is there any other way to find eq. resistance . if yes please tell me.

 

You might consider giving Teszla some hints (not solutions) on a related thread ...

We can't comment on your method unless we see what you've done. How about posting your solution (say) for adjacent nodes. Then you won't be giving anything away on Teszla's problem.

 

pls post your lengthy solutions..hehe..

so that we know that you've tried solving this.. if you said that you have found the answers, why not stick on those lengthy solutions? sometimes its the only solution..

the method is not too lengthy unless u do it properly
