What is surprising thing that happens in a superconductor?
Zero resistance.
What is the surprising thing that happens in a superconductor?
Zero resistance.
How does length affect resistance of a wire?
In general, the longer the wire the greater the resistance. The only time that this is not so is when the wire is a superconductor, in which case the resistance is always zero.
What are the uses of a superconductor?
Superconductors have zero resistance, and are used in powerful magnets for MRI etc, and magnetic levitation.
What happened unexpectedly when mercury was cooled to near absolute zero?
The mercury lost all resistance and became a superconductor.
What resistance does a superconductor have?
An ideal superconductor has exactly zero losses, thus resistance is zero.
Does a super conductor have infinite resistance?
A superconductor has zero electrical resistivity below a specific temperature called the superconducting transition temperature.
Electron move without potentiel difference in a conductor?
No. In a good conductor you simply need less potential difference than in a bad conductor, to get the same current. But if you have zero voltage, you will also have zero current. Unless you have a superconductor (zero resistance), and the current is already flowing.
What is surprising thing that happens in a superconductor?
Zero resistance.
What is the surprising thing that happens in a superconductor?
Zero resistance.
What must happen for a superconductor to work?
Super conductor will have zero resistance or zero resistivity. This happens when the temperature of the conductor reaches a very low temperature known as critical super conducting transition temperature. In case of mercury it will be 4.2K.
Which is an example of a superconductor?
A superconductor is a material with extremely low resistance to an electrical current. Many are metals or the like which have been supercooled to temperatures approaching absolute zero. Examples are mercury, lead and tin
Does a conductor have zero resistance?
No
Are copper and silver super conductors?
No. A conductor is a good carrier of electricity or heat. A superconductor is a material in which the resistance to electrical flow is zero. Silver and copper are fairly good conductors, but some energy is lost.
How does length affect resistance of a wire?
In general, the longer the wire the greater the resistance. The only time that this is not so is when the wire is a superconductor, in which case the resistance is always zero.
What are the uses of a superconductor?
Superconductors have zero resistance, and are used in powerful magnets for MRI etc, and magnetic levitation.
What is super conductor?
its basicly a conductor that is below a certain temp. A superconductor is a material with an extremely low electrical resistivity (up to zero) under a specific temperature.
