Consider four conducing materials copper, tungsten, mercury and aluminum with resistivity $ρ_{C}, ρ_{T}, ρ_{M}$ and $ρ_{A}$ respectively. Then :

Answer:

Solution:

$\begin{array}{l} ρ_{M} = 98 \times 10^{- 8} \end{array} Ω m$

$\begin{array}{l} ρ_{A} = 2.65 \times 10^{- 8} \end{array} Ω m$

$ρ_{C} = 1.724 \times 10^{- 8} Ω m$

$ρ_{T} = 5.65 \times 10^{- 8} Ω m$
