Uses of Copper Wire
Copper has been the most favored metal for electrical wiring and connectors for centuries since the invention of the telegraph and electromagnet. Its growth accelerated with the introduction of the telephone in 1876. For nearly 200 years, copper has been extensively used in various electrical settings, telecommunications, power generation, transmission, and distribution. Reddish-brown in color, copper is a highly ductile and malleable metal. It can be stretched and drawn into wire strands as thin as human hair. The metal has a high thermal and conductivity and can be put to many uses. Among all the uses of this versatile metal, 60% of copper is used in making electrical wires. Copper wire: what makes it popular in electrical wiring? All metals have some amount of resistivity against electric currents and hence they need a power source to push the current through them. The lower the resistivity and better is the conductivity. Copper has a low-level of resistivity, makin...
