Question

answer this question anyone​

Answer 1

a) the wire is cut into 5 equal parts  and resistance is R

let resistance of each part be R'

                     so, 5R'=R

           therefore R'=R/5

R:R'=5:1

b) for parallel,

1/Reff=5/R+5/R+5/R+5/R+5/R

so, Reff=R/25 Ohm

c) for series,

Reff=R/5+R/5+R/5+R/5+R/5

Reff=5xR/5

=R Ohm

hope it helps
