Copper can be drawn into wire because its elastic strength is lower than its tensile strength. If it were the other way around the copper would be brittle and break from being drawn.
To draw wire from copper it is usually annealed first (heated to reduce its elasticity) then drawn into rods through a thimble, then progressively drawn though smaller and smaller dies to reduce its diameter to the preferred gauge or size. As the copper is drawn through the dies it heats up from friction and actually needs to be cooled to prevent it from breaking, as this annealing actually reduces the tensile strength of the copper as well.
*elastic strength is the strength of material that resists permanent deformation of the material. Tensile strength is the resistance to the material being pulled apart.

How do you wire the last fixture in a parallel circuit?
The last fixture in a parallel circuit is wired the same as the first. In North America, all of the fixtures are wired black wire to black wire and white wire to white wire. The black wire being the "hot" wire and the white wire being the neutral wire.
Why would an electric wire be covered with an insulatos such as plastic?
Plastic being nonconducting, it avoids electrocution when covered around electric wire.
How far does DC voltage travel?
DC Voltage is kind of like water pressure. It needs a conductor (usually a wire) in order to travel. The same way you need a garden hose to carry water pressure. Voltage will drop due to resistance in a very long conductor if a significant current is being drawn.
Electricity traveling through a wire is an example of what?
Energy being transferred from place to place
Can current pass throug one thick conductor?
Wire is sized to carry current, it doesn't matter whether the voltage is AC or DC. The larger the diameter of the wire the more current it is allowed to carry.
What is the property of being able to be drawn into a wire?
The property of being able to be drawn into a wire is referred to as ductility. Materials that exhibit ductility can be stretched into a wire without breaking. Ductility is a key characteristic of metals like copper and gold.
Can iron be drawn into wire?
The ability to be drawn into a thin wire is a property known as ductility. Iron has ductility.
Does copper wire insulate?
The insulation on a wire is applied after the wire is drawn to size.
How much length of wire can be drawn from 1gram of gold?
Approximately 2 kilometers of wire can be drawn from 1 gram of gold due to its malleability and ductility properties. Gold is known for being able to be stretched into long, thin wires without breaking.
What if a metal is - it can be drawn into a wire?
It is ductile.
Can a wire be drawn out of wood?
No, wires cannot be drawn out of wood because wood is not a suitable material for making wires. Wires are typically made from metals such as copper, aluminum, or steel due to their conductivity and malleability, which wood lacks.
A term used to describe a material that can be drawn into a long wire?
A substance that can be drawn into wire is indeed called ductile
What substance can be pulled or drawn into a wire?
Ductile
What is the property of being able to be drawn pulled or extruded through a small opening to produce a wire?
Ductility is the property that allows a material to be drawn, pulled, or extruded through a small opening to produce a wire. Materials with high ductility can be easily stretched into thin wires without breaking.
What is the substance that could be pulled or drawn into wire?
A substance that can be pulled or drawn into wire is called ductile. Metals such as gold, silver, and copper are known for their ductility, which allows them to be stretched into thin wires without breaking.
Can lead be drawn into wire?
No, lead is not a suitable material for making wire. Lead is a soft and heavy metal that does not have the necessary properties to be drawn into thin, flexible wire like other metals such as copper or aluminum.
Can be drawn into thin wire?
The metallic property of ductility allows it to be drawn into thin wires.
