Why graphite conducts electricity?
467297
The structure of graphite is planer. There are planes of carbon atoms well bonded together. Between these planes there are more electrons (I think) - but they are free to move. \n\nWhen you apply a voltage, these electons do move - and moving electons is current - ie it conducts

It is energetically more stable for carbon atoms to have the configuration of graphite at atmospheric pressure.  However, under lots of pressure, it obviously favors diamond.  It doesn't change back because even though it is more favorable to be graphite, it is much harder for carbon to do the changing necessary.  It's like, dropping a ball, if you drop it inside a 20 story building, it'll still only hit the floor in front of you.  It would have less potential energy on the 1st floor, but it would have to have lots more energy than it does to get there.

You are confused.  Electrons don't conduct electricity.  They, collectively, make electricity.  They do work by going from high potential energy to low potential energy.  The potential energy is usually caused by concentration of charge, because like charges repel each other.  The movement of electrons is what we call electricity.  Charge is a measure of the difference between number of protons and number of electrons, if you multiply the difference by the charge for one electron you get the charge.\nA coulomb is a unit designed to be more usefull than the charge on an electron because it is large enough to work easily with..

not electrically conductive. carbon is the only non metal conducting element. and as for that idiot who says yes because they use it in batterys...sulphuric acid...is an ACID... ie donates H+ ions and thus leaves a - charged end behind and ions in solution will allow a current to flow

so that it gets ionised during electrolysis and the ions help in the conduction of electricity....

Electricity is  flow of electrons in a conductive material like copper or any metals.  The atoms in the conductor are passing the electrons to the next atom in sequence (current flow in Ampere unit). \n\nAnalogy: \nYou can imagine people in line, passing balls in sequence to the next person until the balls reached the other end.\n\nThe force behind the movement of electrons (potential difference in Volt unit), is due to the excessive supply of electron (negative) from one end and lack of supply (Positive) from the other end. (They flow downstream like water).\n\nImagine if you connect two ends of wire to the positive and negative side of the battery. (But don't do it. That is called; short circuit)\n\nIf the wire is cut in the middle and you connect a light bulb between the two cut ends, The light bulb will glow. \n\nHere is the reason;\n\nBecause the light bulb filament (also a metal but doesn't melt easily) is smaller than the wire conductor and does not easily allow the passage of electron (resistance in Ohm unit), The flow of electron will be restricted to a certain amount (like a bottleneck in a pipe) this restriction will cause heat and light due to friction.\n\nMy best tailored answer for you ;=)

- The bonds between graphite layers are weaker that the bonds within graphite layers \n\nThis is how pencils work, a layer slides off by rubbing it against paper.

Simply put, it's not a conductor. \n\nhttp://jchemed.chem.wisc.edu/JCEsoft/CCA/CCA1/MVHTM/R0540/S567.HTM

Friction causes the electrical charge. Touch something rubber to kill it. Touch metal to continue the conduction thus shocking yourself or others. Break the curcuit.

electricity passes through the wire in the light bulb. as it goes through the curved part, it heats up because it has to push its way through ( meatphorically speaking). By heating up it emits thermal energy (heat) and light energy, and thanks to this, you can read this answer at night, all for this moment. ;)

Used to be lead, wood, metal and rubber.  Now they use graphite instead of lead.

Basically, when you rub two certain materials, you will create static electricity, which is named that way because the charges do not _flow_, i.e. there is no current.\n\nNot so basically, but still very primitively, there exist two forms of material: ones that "likes" to "steal" electrons, and ones that "likes" to "give" electrons. Whenever these two are put next to each other, the electrons "jump" from one substance to the other, causing a potential difference, and possibly a spark (if the potential difference is high enough).\n\nRubbing two such materials does not cause this effect. It is a common misconception; when you rub two things you are simply increasing the surface area of contact between the two such substances, thereby creating a more noticeable effect.\n\nand the check spelling button screwed up some of my spelling. fix it yahoo! people, please. especially with the word 'effect' which was changed to 'effectt' and the plural of some words.

Carbon, the element, comes in three forms. These are graphite, diamond and the other (non christoline). Each is used in many ways for many things.\n\nGraphite is a flat form of carbon molecule. The cristles are hexagonal. These crystals can slide over each other acting as a lubricant. Graphite is used as a lupricant - often calles "graphite greese". It is also used in "lead" pencils.\n\nTetrahedron crystals are found in diamonds. These are not flat. These are used in jewelery, cutting tools, grinders etc. This is because diamonds are very hard and long lasting.\n\nNon crystaline carbon is used in chamical reactions. Coal is baked in baked in coke ovens to make "coke" (not the drink) which is then used in the manufacture of iron and steel.\n\nCardon is used, by plants, to make sugars, which it turn, we eat to give us energy. As our bodies "burn up" these sugars, we create carbon dioxide which we exhale.\n\nEverywhere you look you see uses of carbon - In timber, carbon fibre, Gasoline the list goes on and on.

its makes for versatile application of the particular element..for instance graphite allotrope of carbon can be used for pencil lead

Conductors allow electricity to flow through them with little resistance.  Resistors resist the flow of electricity.

Its is the amount of resistance.  Same reason the wire in a lightbulb grows.  There is some level of electrical resistance, even in conductive materials.  The resistance creates heat and eventual combustion.

In the sense of a motor the terminology is from the the early days when wire fibers were used then later found that a brush made of carbon can deliver the power without wearing out the commutator. The carbon brush being of softer material would easily be replaced when worn down.\n\ncheck out the following link:
