Graphite is an electricity conductor; I suppose that the discoverer of this property is unknown.

Does pencil lead have coal in it?
Pencil lead does not have coal. Pencil lead contains graphite.
Is a pencil poison?
If your asking if the pencil has Lead, then the answer is that most pencils do NOT have lead in them anymore.
What is a pencil lead made of?
Pencil lead is made of graphite and clay. Newer recipes for pencil lead use waxy polymers to bind the graphite to produce a lead that does not snap when the pencil is flexed.
Why element makes diamonds and pencil lead?
Carbon constitutes pencil lead, charcoal and diamond. Although they appear different in appearance, they are chemically the same. Diamond is shiny and hard due to the crystalline arrangement of carbon atoms in it. Graphite or pencil lead has such an arrangement, that there are free electrons which make it a conductor of electricity. Elements like this, which are chemically the same but exhibit different physical properties are called allotropes, and the phenomenon is termed as allotropy.
Can a mechanical pencil give you lead poisoning?
Due to the fact that most pencil lead is graphite, you can't get lead poisoning. :)
Will a line drawn by a pencil conduct electricity?
we know that graphite(pencil lead)conducts electricity.a line drawn by the pencil contains graphite particles.then why can't it conduct electricity?
Are there any non metals that are conductors of electricity?
Some metalloids, such as silicon, conduct electricity. Graphite(pencil lead) also conducts a bit.
What is lead in pencil?
Graphite is present in pencil leads. it is composed of carbon atoms covalently bonded with each other, and 1 free valence electron in each atom (which explains why graphite/pencil-lead conducts electricity)
Will pencil lead conduct electricity?
Yes, Pencil Lead does conduct Electricity. Copper, Gold and Silver though are the best conductors.
Is pencil lead a conductor of electricity?
yes pencil lead is a conductor it is made of graphite(a form of carbon) which is good conductor of electricity
Is the lead of a pencil (graphite) can conduct electricity.?
Yes.
How do you conduct electricity from anemometers?
through pencil lead.
Which part of a wooden pencil is the best conductor of electricity?
The graphite or black part in the center. People sometimes call it lead but that is misleading. Pencils used to be made of lead until it was discovered that lead is toxic. Now they are graphite, a form of carbon.
Does a pencil conduct electricity?
Yes the center carbon or lead can conduct electricity. The carbon in the pencil is also used in resistors for resistance in a circuit.
Is pencil lead a conductor?
Yes, pencil lead is a conductor of electricity. Lead is a metal. Most metals are good conductors of heat and electricity. Assuming of course you mean pencils back when lead was actually used as the writing medium in the pencil, then yes. Other than that, pencils nowadays are made using graphite as the writing medium. But graphite too can conduct electricity.
Why can pencil lead can be used to make a light bulb?
A "pencil lead" is a mixture of the graphite allotrope of carbon mixed with clay and baked hard. While a pencil lead will conduct electricity, it can not be used to make a light bulb.
What effect does pencil lead have on the flow of electricity and on a motor and speed of the motor?
If the question is asked correctly and if graphite conducts electricity (I don't know if it does) then any pencil lead on a conductor would infinitesimally decrease the resistance of the circuit, too small to matter. Metal shavings and other debris that conduct electricity are very dangerous because very often it falls into places where you do not want current to flow. If you are referring to "penciling" the insulation on a conductor then please restate the question and I will be happy to answer it for you.
