Question

a piece of wire having a resistance r cut into 6 equal parts how will the resistance of each part compared with the original resistance​

Answer 1

Answer:

each part will have a resistance of r/6ohms

Answer 2

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
