Question

A copper wire of length 2m and area of cross section 1.7 *10^-6 m^2
has a resistance of 2* 10^-2
ohms. Calculate the resistivity of the copper wire.

Answer 1

Explanation:

length = 2m

area of cross section = 1.7×10^-6 m²

resistance = 2×10^-2 ohm

using R=rho l / A

and substitution of values
