Is it true that nonmetals are good conductors of heat and electricity?
No, nonmetals are generally poor conductors of heat and electricity. This is because they do not have freely moving electrons that can carry the heat or electric charge effectively. Metals, on the other hand, are good conductors due to the presence of delocalized electrons.
What is the difference of insulators and conductors?
Insulators: We define insulators as, A nonconducting material that provides electric isolation of two parts at different voltages. To accomplish this, an insulator must meet two primary requirements: it must have an electrical resistivity and a dielectric strength sufficiently high for the given application. The secondary requirements relate to thermal and mechanical properties. Occasionally, tertiary requirements relating to dielectric loss and dielectric constant must also be observed. A complementary requirement is that the required properties not deteriorate in a given environment and desired lifetime. Conductors: We define conductors as, A substance or medium that conducts heat, light, sound, or especially an electric charge.For Example,Metal wires, cables, rods, tubes, and bus-bars For further information about conductors check out the following link: http://www.answers.com/Conductors
What are conductors insulators and semi conductors and super conductors?
b
Are scissors conductors?
They are Conductors, not much for insulation though. Differences between conductors and insulators? Conductors let energy such as electricity .
Is it true that shield wires conductors located above the phase conductors protect the phase conductors against lightning?
Yes, but they're not 'phase' conductors, they're 'line' conductors.
Define bad conductors of electricity?
Bad conductors of electricity are materials that do not easily allow the flow of electric current. They have high resistance to the movement of electrons, resulting in very low conductivity. Materials like rubber, glass, and plastic are considered bad conductors of electricity.
If ther are more than conductors in the raceway the ampacity of the conductors must be derated?
Ampacity must be derated depending on the number of conductors and the ambient temperature. In the Canadian Electrical Code Table 5C denotes derating for the number of conductors. 1-3 conductors = 100% load 4-6 conductors = 80% 7-24 conductors = 70% 25-42 conductors = 60% 43 or more conductors = 50%
Are metale uaually conductors or insulators?
Metals are conductors.Metals are conductors.Metals are conductors.Metals are conductors.
Why do metal spoons heat up instead of expanding?
They are conductors of heat They are conductors of heat They are conductors of heat
Are humans conductors or insulators?
humans are not insulators, but are conductors!
What examples of materials that are conductors?
All metals are conductors. Gold, silver, copper, aluminum and iron are used as conductors.
What are some good conductors?
There are many great conductors in the world. These conductors include but are not limited to water and many metals.
