Question

uniform wire with a resistance of 27 S2 is divided
into three equal pieces and then they are joined
parallel. Find the equivalent resistance of the parallel combination​

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
