What is conductors insulators superconductors and semiconductors rank in order of least resistance to most resistance?
Superconductors have no resistance. Conductors have low resistance, semiconductors have intermediate resistance, and insulators have high resistance.
What shows how conductors insulators superconductors and semiconductors rank in order of least resistance to most resistance?
Superconductors have no resistance, making them the best conductors. Semiconductors have moderate resistance. Conductors have low resistance, making them better conductors than insulators, which have high resistance, making them the poorest conductors.
Which has the lowest resistance semiconductors superconductors insulator conductor?
Superconductors have the lowest resistance of all materials, with resistance dropping to zero when they are cooled below a certain critical temperature. Conductors have lower resistance than semiconductors and insulators, which have significantly higher resistance and do not conduct electricity as effectively.
How are superconductors different from conductors?
In superconductors, no electricity is wasted because there is no resistance to the flow of electrons. In conductors any electricity not used, is wasted.
What is the definition of low temperature supercoductors?
In a way, all currently existing superconductors are "low-temperature", but some more so than others. The traditional superconductors work up to about 20 K (or minus 253 Centigrade); more recent "high-temperature superconductors" work up to 100 K or so. 100 K is still minus 173 Centigrade, but it is much "hotter" than the traditional superconductors. The new "high-temperature" superconductors apparently work different than the old-fashioned ones; at least, the theory that explains the traditional superconductors fails to explain how the new superconductors work.
How is sound insulator similar to and different from a heat insulator?
Sound insulators are similar to heat insulators in that they both aim to reduce the transfer of energy, but they work in different ways. Sound insulators absorb and dampen sound vibrations, while heat insulators reduce the transfer of heat through conduction, convection, or radiation. Materials that are good sound insulators may not necessarily be good heat insulators and vice versa.
Why superconductors are not used often in everyday activities?
Because at present all superconductors must be super-cooled in a coolant such as liquid nitrogen to become superconductors.
What are conductors and insulators of electricity?
Conductors are materials that pass electrical current easily, that is, with low resistance. Insulators are materials that do not pass electrical current easily, that is, they have high resistance. Conductors are ordinarily metals, and insulators are ordinarily nonmetals. Some examples of conductors are: Silver, Copper, Carbon, and Aluminum. Some examples of insulators are Glass, Nylon, and Wood (as well as Air and Vacuum). Conductivity is a function of the mobility of Electrons in the materials in question. Conductors have high mobility and conductors have low mobility. Semiconductors are materials that have some properties of both conductors and insulators. Germanium and Silicon are well known semiconductors. Superconductors are materials that pass electrical current with zero resistance. All known superconductors perform this function only at very low temperatures, far below those encountered in Earth environments (i.e. from around 77 degrees above absolute zero down, or, in other words, below about -320 degrees F).
What are most modern high temperature superconductors made of?
Resistance decreases with the decrease of temperature. Superconductors are made by lowering the temperature.
Why are scientists trying to make superconductors that can work at warmer temperatures?
Because refrigerating superconductors to the cryogenic temperatures needed by current ones is expensive, severely limiting the applications they are used in.Metallic superconductors need cooling to the temperature of liquid helium.Copper oxide ceramic superconductors need cooling to the temperature of liquid nitrogen.Room temperature superconductors, if they exist, would need little or no cooling.
How ARE superconductors different from solid liquid and gasses?
The question is like asking "what's the difference between a red shirt and one made of nylon"? Superconductors are also solids. I don't think there are any liquid or gaseous superconductors (weird stuff may happen in portions of the phase diagram far removed from ordinary Earthly conditions, so I'm not absolutely positive that, say, liquid metallic hydrogen or whatever isn't superconducting, but any superconductors we can actually make on Earth are solids).
Insulators offer resistance to the flow of electric current.?
Yes, different grades of insulators can offer different levels of resistance to current flow of electrons within a closed circuit. For instance the flow of current would be different between wood and rubber, both insulators.
