Question:
Consider four conducting materials copper, tungsten, mercury and aluminium with resistivity $\rho_{C}, \rho_{T}, \rho_{\mathrm{M}}$ and
$\rho_{A}$ respectively. Then :
Correct Option: , 2
Solution:
(2) $\rho_{M}=98 \times 10^{-8}$
$\rho_{A}=2.65 \times 10^{-8}$
$\rho_{C}=1.724 \times 10^{-8}$
$\rho_{T}=5.65 \times 10^{-8}$
$\therefore \rho_{M}>\rho_{T}>\rho_{A}>\rho_{C}$
