The resistance of a wire of length 10 $m$ is 5

$Ω$ . If the area of cross section of the wire is

$9 \times 10^{- 7} m^{2}$ .

Determine its,

(i) Resistivity

(ii) Conductance, and

(iii) Conductivity.

[Note: Enter the answer up to two decimal places.]

Answer:

(i) Resistivity,

$\rho$

$=$

$\times 10^{- 7} Ω m$

(ii) Conductance,

$G$

$=$

$mho$

(iii) Conductivity,

$\sigma$

$=$

$\times 10^{7} mho m^{- 1}$
