Compare the resistances, Physics

Assignment Help:

Two resistances have lengths in the ratio 1:4 and radius 1:2,specific resistances in ratio 3:1. compare their resistances.

Solution)
Given lengths l1=1

                         l2=4

Given radius r1=1

                        r2=2

 Given  specific resistances Ρ(rho)1=3

               Ρ2= 1

we know the R=Ρl/A

              R1/R2=3/1.
