    When Is Carbon an Electrical Conductor?

    By Adam Weiner Posted on 9.30.2008 13 Comments

    And the $64,000 question is ... does graphite conduct electricity? It certainly does! The video demonstration displays this quite convincingly. Graphite is an interesting material, an allotrope of carbon (as is diamond). It displays properties of both metals, and nonmetals. However, like a metal, graphite is a very good conductor of electricity due to the mobility of the electrons in its outer valence shells.

    smurrah.....either you have never studied anything that has to do with electricity, or you sat and giggled at the wall during basic DC theory in class. If you dont know what your talking about please refrain from arguing with a magizine that is pretty much dedicated to knowing about simple things as this..... think about it like this: if resistance caused so much heat, your house would go up in flames everytime you turned something on. Since you are posting ridiculous comments on here, I am going to guess your house is still intact....
