What else can I help you with?
Name three of the best conductive materials.?
Leaving aside superconductors: graphene, silver, copper.
What do you call materials with a resistance of 0 W?
superconductors
Which of these is a drawback of hydraulic fracturing?
Earthquakes
What is a drawback to use of oil shale to produce energy?
Expense
Why are superconductors efficient than ordinary conductors?
It doesn't. Superconductors have no (virtually no) losses, they are purely inductive. This has no bearing on how current flows. Normal conductor will heat up due to resistive losses of the line (I^2 R losses), while a superconductor shouldn't.
What is a drawback to using superconductors?
They are usually quite expensive and require very low operating temperatures.
What is the difference between superconductors and normal conductors?
Normal conductors have resistance which restricts the flow of electricity and wastes some of the energy as heat. The resistance increases with the length of the conductor. Superconductors have close to zero or zero resistance and a few other properties, but the resistance is the most important one because it means electricity can flow more efficiently through it. The drawback is that all the superconductors we know of today have to be cooled down to EXTREMELY low temperatures to achieve superconductivity.
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 most modern high temperature superconductors made of?
Resistance decreases with the decrease of temperature. Superconductors are made by lowering the temperature.
What is an antonym for drawback?
A drawback is a disadvantage. Thus, the opposite (or antonym) of "drawback" is "advantage"
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.
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 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 has the author Franklin Curtis Mason written?
Franklin Curtis Mason has written: 'The tunnel effect in superconductors' -- subject(s): Superconductors
What has the author Anatoli Larkin written?
Anatoli Larkin has written: 'Theory of fluctuations in superconductors' -- subject(s): Fluctuations (Physics), Superconductors
Why do superconductors float?
Superconductors float due to the Meissner effect, which causes them to repel magnetic fields, allowing them to levitate above a magnet.
How are superconductors different from insulators?
Superconductors are materials that let current or electricity pass through them. Insulators are materials that don't allow current or electricity to pass through them. Superconductors are mostly all metals. Insulators are wood, plastic, and paper.
