because copper is a great conductor of electricity. graphite is also conductor of electricity. they use it in arc lamps, for example.
graphite is an allotrope of carbon, which means that it is made of carbon rings. the rings are loosely bound together, so they flake off easily (why they use them in pencils). this makes it difficult to form into wires (microscopic wires are a different story, more about that at the end)
The reason it conducts electricity is the structure of the rings. If they were arranged differently (like in a diamond) it would not conduct electricity. Diamonds are insulators.
In fact, nanowires are very small conducting wires of graphite flakes folded onto themselves into tubes. They are the cutting edge of research in this field of physics.

∙ 11y agocopper wire conduct better than other metals becuase of the electrons , the top elctron shell only contains 1 electorn meaning it can flow with ecltrcity current easyer

A reddish-orange element used for electrical writing?
Copper its symbol is Cu and its atomic number is 29.
What mineral is used for electrical wiring?
Wires are generally not comprised of minerals, but metals. Examples are copper, aluminum, and gold. There are some insulation systems that use "rock wool" (which is mineral based), for high temperature or high radiation exposure.
In what part of car copper is used?
wiring, starter, alt etc
What elements have the lowest electrical conductivity?
It is sulfur that is the worst electrical conductor, followed by phosphorus and iodine. Want to see a table of the elements listed by conductivity? Sure you do. There is a link below that will take you to one.
How can you use copper in every day life?

Why is copper better than aluminum for most electrical wiring?
because it is. its the way of life.
What can pure copper be used for?
Pure copper is used for electrical wiring. Pure copper conducts electricity better than impure copper.
How much electrical wiring is copper?
Copper holds a 92-percent market share of electrical wiring in building (8 percent aluminum).
Used in electrical wiring and pennies?
copper
Why is copper good for electrical wiring?
Copper is an excellent conductor of electricity. Among metals it is second only o silver, which is too expensive for practical use in wiring. Copper is also extremely ductile, meaning it can be easily drawn into wires without breaking.
What is copper use for in Puerto Rico?
Electrical wiring.
What material used for electrical wiring in cars?
Most automotive wiring is stranded copper.
What metals are used in wiring in a car?
Electrical auto wiring is almost all copper.
Why is gold not used as an electrical wiring?
Too expensive, it would be stolen (as it is there are people stealing copper electrical wiring, and copper is much cheaper than gold).
What element is used in wiring?
Copper is the cheapest and widely used element in wiring. Copper alloys are also used for the long run, increase flexibility and better handle of temperature changes.
What are practical uses of copper?
The main use is in electrical wiring.
