Give reasons: Aluminium wire is used to make transmission cables.

(N/A) $Ag$,$Cu$,and $Al$ are among the best conductors of electricity. $Ag$ is an expensive metal and $Ag$ wires are very costly. $Cu$ is quite expensive and is also very heavy. $Al$ is a very ductile metal and is lightweight. Thus,$Al$ is used in making wires for electrical transmission.
