Answer:if a wire of resistance r is cut into 6 equal parts the length will decrease but the the area of cross section and the resistivity e will remain same therefore the resistance of each part will be come one sixth of the original resistance
Explanation:
1/R=1/(r/6)+1/(r/6)+1/(r/6)+1/(r/6)+1/(r/6)+1/(r/6)
1/R=6/(r/6)
1/R=36/r
R=r/36
Therefore total resistance off the wire will decrease by 1/36 of initial resistance
