No. Diamond is a thermal conductor, but an electrical insulator.
It would help if you specify whether you are talking about thermal conductivity, or electrical conductivity. Diamond certainly doesn't has the highest electrical conductivity. Its thermal conductivity is one of the highest known, and - if a synthetic diamond is made from pure (99.9%) C-12, it is indeed the highest. The Wikipedia article attributes this to a strong covalent bonding.
Yes, they do.
Neurons.
neurons
- Neurons*Thus transmit electrical messages from one area of the body to another area of the body.
Graphite conducts far more electrical conductivity vise versa the diamond conducting far more thermal conductivity. Diamonds are hard. Graphite is soft.
electrical conductivity of graphite?
There is none. Most minerals have no electrical Conductivity!
Uranium is a metal and as such, it has excellent electrical conductivity.
Thermal conductivity refers to the conductivity that is associated with heat. Electrical conductivity refers to the conductivity that is associated with electricity.
Thermal resistance: diamond Electrical resistance: copper Optical resistance: quartz
Electrical conductivity is a physical property, not a change.
