Copper and aluminum are good conductors. Other conductors like silver aren't used to make electric wires because copper and aluminum are cheaper but have the same properties.
Along wires. Copper wires underground or aluminium overhead.
Copper is always preferred in houses because it conducts electricity better and does not corrode on the surface as easily as aluminium. But for overhead electric wires, aluminium is preferred because it is much lighter and the pylons don't have to be so massive.
Copper wires are used as connecting wires because copper is an excellent conductor of electricity, allowing for efficient flow of electric current with low resistance. Additionally, copper is readily available, malleable, and cost-effective, making it a practical choice for wiring applications.
Steel is not used as an electrical conductor because, although it is a conductor, it's not a very good conductor -as is copper and aluminium, for example. A steel-wire core is used, however, to reinforce aluminium conductors on transmission tower lines
Copper is an excellent conductor, ductile (can be drawn easily), and reasonably economical. For bare conductors, copper oxidises and the oxide coating prevents further corrosion. While it is heavier than aluminum, it is stronger. The alternative, aluminium, is cheaper than copper, but not as good a conductor. Aluminium is lighter, but weaker, and aluminium transmission lines require a steel-core for strength. Aluminium conductors suffer from 'cold flow', which means that aluminium conductors secured with screw terminals tend to work loose over time. Copper doesn't do this, so copper is preferred for residential/commercial electrical wiring systems.
No, you need DC.
The copper wires used connect. Because conductivity of Cooper higher than aluminium but price of Cooper higher than aluminum. If compare between copper and aluminium cable can see at the same current rate diameter of aluminium cable is larger than copper cable.
Copper has been used lately in wires and cables like coaxial and electric wires.
Copper is frequently used for electrical wires. Aluminium is cheaper but breakable.
Copper and aluminum used for electric wires
copper is cheaper to manufacture and easier to bend then steel
Copper is commonly used to make electric wires because it is an excellent conductor of electricity, allowing for the efficient transfer of electricity through the wires. Copper is also highly conductive and ductile, making it easy to shape into wires for various electrical applications. Additionally, copper has good corrosion resistance, ensuring the longevity and durability of the wires.
