Question

Name the materials which have

a. very low resistivity.

b. high resistivity.

Answer 1

Resistivity is the ability of a material to resist the flow of current.

a. The materials such as silver and copper have very low resistivities. The resistivity of silver is $1.60\times {10}^{-8}\Omega m$ and the resistivity of copper is $1.62\times {10}^{-8}\Omega m$.

b. The materials such as tungsten and nichrome have high resistivities. The resistivity of tungsten is $5.20\times {10}^{-8}\Omega m$ and the resistivity of nichrome is $100\times {10}^{-6}\Omega m$.
