Start by disconnecting one alligator clip from the bulb . a pathway that allows an electric current to flow freely through. For example charcoal and graphite which are allotrope of Carbon act as conductor, as opposed to diamond, which has a different crystal structure and acts as an insulator. Question 23. Graphite has a lot of resonance structures, which allows the electrons to 'move' through the layer. Materials that conduct electricity are conductors. However, electrical charge or heat is not allowed to pass through an insulator. Reason (R): Graphite is soft in nature on the other hand diamond is very hard and brittle. Whereas in diamond, they have no free mobile electron. Conductors are used to conduct electric current from one place to other. But it's not up there with copper and silver. The reason graphite is a good conductor of electricity is because of the presence of delocalised electrons, as each carbon atom forms only three covalent bonds with three other carbon atoms.
