Why is copper and not silver used to make electrical wires?
Copper is a metal thus, it has strong metallic binds and the free electrons allow them to conduct electricity.
The problem with silver is that it gets tarnished with time.
Also, it is more exensive than copper.
We know that copper as well as silver are good conductors of heat and light..
Why is copper used for electrical wiring?
Why is copper used for most electrical wiring? … The lower the level of resistivity, the more electrical conductivity a metal has. Copper has low resistivity, and therefore is an excellent conductor. Copper is also less oxidative than other metals.
What is the difference between copper and silver wire?
Though silver wire is roughly 7 percent more conductive than a copper wire of the same length, silver is a significantly rarer metal than copper. … Silver wire, however, is generally reserved for more sensitive systems and specialty electronics where high conductivity over a small distance is prioritized.
Is copper better than silver?
Although silver is a slightly better electrical conductor than copper (about 5% better), it is currently over 89 times as expensive (using today’s spot prices for each metal). … Although it is the best conductor, copper are used more often in electrical applications because copper is less expensive than silver.
What is the silver coating on copper wire?
Silver plated copper wire is composed of a copper core covered by a concentric silver plating. This material combines the advantages of copper, such as the conductivity, with the bright and shiny surface of silver. In addition, the silver coating provides high corrosion resistance.
