let wire resistance = R
now wire cut into 3 pieces so resistance of each wire = R/3
resistance in parallel
1/Rp= 1/(R/3)+1/(R/3) +1/(R/3)
1/Rp = 9/R
Rp = R/9
Result Resistance became 1/9 times of wire resistance
now wire cut into 3 pieces so resistance of each wire = R/3
resistance in parallel
1/Rp= 1/(R/3)+1/(R/3) +1/(R/3)
1/Rp = 9/R
Rp = R/9
Result Resistance became 1/9 times of wire resistance
