Give three reasons why pure copper is a
good choice for making electrical wires.
Answers
Answer:
Copper electrical wires are safer to use than wires made of most other conductive metals because they are resistant to heat. As you can see, copper is the preferred metal for electrical wires for several reasons. It has high electrical conductive; it's inexpensive; it's ductile; and it's thermal resistant.
why pure copper is a
good choice for making electrical wires.
Answer
All metals have some amount of resistivity to electrical currents, which is why they require a power source to push the current through. The lower the level of resistivity, the more electrical conductivity a metal has. Copper has low resistivity, and therefore is an excellent conductor.
Copper coilingCopper is also less oxidative than other metals. Oxidation happens when the oxygen and moisture in the air react with a metal’s surface. This reaction corrodes the metal and produces a film-like covering, like rust on steel. Copper does not rust, but will produce a greenish patina called copper oxide. Unlike rust, however, this covering actually protects the metal from further corrosion and doesn’t interfere with conductivity.
