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.

∙ 9y agoThe molecules of a superconductor are arranged in a way that allows their electrons to flow through it with almost nothing getting in their way. The best superconductors need to be chilled to an extremely low temperature in order to get their molecules so tightly organized.

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%
What is a drawback to superconductors?
One of the main disadvantages of copper cables is that copper is expensive compared with other metals such as iron or aluminum. Copper can also corrode, though not as much as some other metals.
What ways are there to convert 480 3 Phase to 208 3 phase?
It depends on your definition of efficiency. 480 can certainly push more power than 208 through the same size conductors, but it would not be efficient to wire a motor for 480 when 208 was all that was needed.
Why the spacing between the conductors of same phase is greater as compared to spacing between different phase conductors in double circuit lines?
I think you mean spacing between line conductors, rather than phase conductors. If there is a greater spacing between line conductors in one circuit, compared with anothercircuit, then the two circuits are operating at different voltages.
How do you write the sentence Our school needs a heating system One that is more fuel-efficient than the current system properly?
Our school is in need of a heating system that is more fuel-efficient than the current system. or Our school needs a heating system more fuel-efficient than the current one.
What is more energy efficient than ordinary backlighting?
Led (light emiting diode)
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.
Why is electrostatic spray gun more efficient than ordinary spray gun?
The electrostatic spray gun is more efficient than an ordinary spray gun because more of the paint gets on to the object being painted. The droplets being charged makes them become attracted to what is being painted, rather than spraying all around.
What are the benefits of quartz heaters over ordinary electric heaters?
Quartz Heaters are unique in a number of ways. Most notably, the design of these heaters is such that it is more efficient than ordinary heaters. This allows it to deliver more heat for less cost.
Will a copper or steel wire of the same length and thickness allow more current to pass through?
Copper is the better conductor. The only materials that are better conductors than copper are either very expensive (such as gold and silver), or superconductors that only work at cryogenic (supercold) temperatures.
What conducts electricity better than gold?
At room temperature, both silver and copper are better electrical conductors than gold.At low temperatures (i.e. close to absolute zero), it's a very different story - many of the metallic elements, all the metalloids and many of the non-metals on the periodic table become superconductors and therefore have zero resistance. In all, 54 elements display superconductivity, although some require high pressure and low temperature.Strangely, Gold, silver and copper do not become superconductors under any conditions that have been attempted to date.
WHY STRANDED CONDUCTERS ARE USED IN POWER CABLES?
Stranded conductors are more flexible than solid conductors.
What do you mean by electrical double wrapped cross joint?
An electrical double wrapped cross joint is just like an ordinary cross joint but double wrapped with electrical tape. It is used where two tap conductors need to extend away from the branch conductor in the opposite direction and is stronger than the ordinary cross joint.
Metals are conductors of heat and electricity?
Yes, but some metals are better conductors than others.
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%
Why are metals better conductors than ceramics?
Metals are better conductors than ceramics because they have a large number of loose electrons. Electricity has loose electrons.
Why does a semiconductor have fewer electrons than a conductor?
Valence electrons only are able to cross the energy gap in semiconductors since it is greater than that of conductors. That is why semiconductors have fewer free electrons than conductors.
