most of the time, copper
Usually copper or some other type of metal element
Water pipes, electrical wire, roofs, statues, coins, wood treatment . . .
copper
It's dependent on the wire's composition. That is, what material it is made of. <<>> The electrical resistance in a wire depends on the wire's length and cross sectional area.
No. Copper wire is made of the element copper. Tungsten wire is made of the element tungsten. Copper wire is made to conduct electricity. Tungsten wire is made for the filament in light bulbs as tungsten does not melt under even very high temperatures.
yes
Copper is on the Periodic Table, anything on the periodic table is an element so copper wire is made from an element.
electrical resistance
It can be used in electrical wires. Actually, in the future a lot of electrical wire may be made mostly of sodium. Google "lightweight composite electrical wire".
Electrical wire can consist of several different elements from Aluminum to copper and even steel. Many types of wire have been made from silver and also gold, depending on the application, and it's no uncommon to plate the wire with another metal to avoid corrosion or rust.
Most wire is made of an electrical conducting metal such as steel, copper, brass, etc. Then to prevent electrical "shorts," a generally flexible, electrically insulating material is used to cover the wire.
