Resistance of a metal wire of length 1 m is `26 Omega` at `20^@ C`. If the diameter of the wire is `0.3 mm`, what will be the resistivity of the metal at that temperature ? Using Table `1.1`, predict the material of the wire.

Options

A. `184xx10^(-6) Omega -m`
B. `285xx10^(-6) Omega -m`
C. `156xx10^(-6) Omega -m`
D. `142xx10^(-6) Omega -m`

Answer

A
