I am just wondering if pure carbon and graphite have the same resistivity?
Resistivity for pure carbon = 3.5 x 10^-3Ωm
Resistivity for pure carbon = 3.5 x 10^-3Ωm
Resistivity is a measure of a material's ability to resist the flow of electric current. It is measured in ohm-meters (Ωm).
No, pure carbon and graphite are not the same material. Pure carbon refers to an element on the periodic table, while graphite is a form of carbon that occurs naturally or can be synthesized.
Pure carbon and graphite have the same resistivity because they both have a similar atomic structure, with delocalized electrons that allow for the flow of electric current. This makes them both good conductors of electricity.
In most cases, pure carbon and graphite can be used interchangeably in electrical circuits due to their similar resistivity. However, pure carbon has a higher melting point and is more chemically stable, so it may be preferred in certain applications.
Yes, there are some differences in the properties of pure carbon and graphite. For example, pure carbon is a brittle solid, while graphite is a soft and slippery solid. Additionally, pure carbon has a higher density and is a better thermal conductor compared to graphite.
