Answer 2

Given

Resistance of wire = 1 ohm

When wire bent in to square then Resistance of each side of square = 1/4 ohm

Equivalent resistance of each side of square = resistance in series + resistance in parallel

Resistance In series = 3/4 ohm

resistance in parallel 1/Rp = 4/3 + 4 = 16/3

Rp = 3/16ohm
