Good conductor of electricity is

Good conductor of electricity is 

(1) dry air 

(2) paper 

(3) kerosene 

(4) graphite 


Answer: (4) Graphite has a tendency to behave very much like metal because the carbon molecules arrange themselves into a lattice structure. The crystal lattice is the same orientation that metal forms, and it allows the free movement of electrons, making it a good electrical conductor. The characteristics possessed by the graphite for conduction is far better than the dry air paper and kerosene and that’s what makes it a good conductor.
