four wires of each 0f the same length diameter and material are connected to form a square,If the resistance of each wire is R.then equivalent resistance accross the opposite corner is

If wires of same material , equal lenth and equal diameter are connected as four sodes of square as shown in left side figure,

then each side hase same resistance R .  Total resistance of side AB and BC is 2R .

Similarly , total resistance of side AD and CD is 2R

Across the corner points A and C , we have total resistance 2R of sides AB and BC is in parallel to total resiatnce 2R of side AD and side CD.

Hence effective resistance across A and C  is  R
