First example,
Copper: It is used in the wiring of houses, and the Internet. It is highly conductive and malleable making it ideal for such
applications.
Second:
Plastic:
It is an insulator, which makes it non-conductive. It is used as a sheath for electrical wires to prevent shorts. It is used widely in the building of homes to run wires all around the house without fire hazard.
Third:
Aluminum: It is a metal that is a good conductor and lighter than copper. It is used in the high voltage wires you see on towers. Since it is strong and light, while being a good conductor, it allows the towers to be spaced far apart to make the building of high voltage transmission lines economical and reliable.
