Answer:

R=resistivity(l/A)

Resistivity= R(A/l)

where

R= resistance

A= area of wire

l= length of wire

Resistivity= 0.011304 ohm meter

Explanation:

R= 5 ohm

l= 1 meter =1000mm

r=0.6 mm

Resistivity= R(A/l)

A= 2 pi r^2 (area of wire ie area of circle)

=2×3.14×.6^2

=2.2608

Resistivity = (5×2.2608)/1000

=0.11304 ohm meter is the answer

Thank you
