Good conductor of electricity is – |
| A. | dry air |
| B. | paper |
| C. | kerosene |
| D. | graphite |
| Answer» D. graphite | |
|
Explanation: Graphite has a tendency to behave very much like a 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 possesses by the graphite for conduction is far better than the dry air paper and kerosene and that's what makes it a good conductor. |
