Textbook Problem

A wire of diameter 0.800 mm and length 25.0 m has a measured resistance of 1.60 Ω. What is the resistivity of the wire?

To determine
The resistivity of the wire.

Explanation

Given Info: The wire has diameter 0.800mm and length 25.0m . the resistance of wire is 1.60Ω .

Explanation:

ρ=RAl

  • ρ is the resistivity of the material of wire,
  • A is the area of cross section of wire,
  • l is the length of the coil,

Area of circular cross section of wire is given by

A=πd42

  • d is the diameter of the wire

Substitute equation for area in the above equation to rewrite ρ .

ρ=Rπd24l

Substitute 1.60Ω for R , 25.0m for l , 3.14 for π  and 0.800mm for d to find ρ
