A) \[2.1\times {{10}^{-7}}\Omega -m\]
B) \[3.1\times {{10}^{-2}}\Omega -m\]
C) \[4.1\times {{10}^{-7}}\Omega -m\]
D) \[5.1\times {{10}^{-7}}\Omega -m\]
Correct Answer: C
Solution :
As, the resistivity, \[\rho =\frac{RA}{l}=\frac{A}{Gl}\] \[=\frac{8\times {{10}^{-6}}}{2.45\times 8}=4.1\times {{10}^{-7}}\Omega m.\]You need to login to perform this action.
