Question

Name the metals which are generally used for making electrical transmission lines.

Answer 1

1. The metals like copper and aluminium are generally used for making electrical transmission lines.
2. These metals have low resistivity and are good conductors of electricity.
3. The resistivity of copper is $1.62\times {10}^{-8}\Omega m$ and the resistivity of aluminium is $2.63\times {10}^{-8}\Omega m$.

Thus, copper and aluminium are generally used for making electrical transmission lines.
