Question

The resistance of a conductor is 27 ohm. If it is cut into three equal parts and connected in parallel, then it's total resistance is
a) 6 ohm
b) 3 ohm
c) 9 ohm
d) 27 ohm

Answer 1

R=27Ω

after dividing them into equal parts,

resistance of each part =9Ω

when connected in parallel,

1/9+1/9+1/9=1/R

3(1/9)=1/R

1/3=1/R

R=3Ω

Answer 2

Answer:

R=27Ω

after dividing them into equal parts,

resistance of each part =9Ω

when connected in parallel,

1/9+1/9+1/9=1/R

3(1/9)=1/R

1/3=1/R

R=3Ω
