Hi Anju,


3 ohm wire cut into 3 equal pieces.........then each wire resistance is 1 ohm


then for the given arrangement: (2 resistors of 1 ohm each in series ) parallel with(1 ohm resistor)


2ohm in parallel with 1 ohm


2*1/(2+1)=2/3 ohm

since the resistance for a given material remains constant. THEREFORE out of three resistors, two are in series and the resultant is parellel with the remaining resistor


            3+3=6


            (6)(3)     = 2


             6+3


  therefore equivalent resistor is = 2 ohm
