What is a superconductor in layman s terms

A superconductor can be understood as a conductor whose resistance to a conductive medium is close to zero! (The conductor resistance cannot be zero, it can only be infinitely close), and usually some special conductor media have superconductivity under ultra-high temperature or ultra-low temperature conditions. We refer to conductive media that have superconductivity under certain conditions as superconductors.

A superconductor is a conductor with a very small resistance, so small that it is close to zero. The existing science and technology can only be achieved in an ultra-low temperature environment (-145 degrees Celsius to -272 degrees Celsius), and if superconductors can be studied at room temperature, it will certainly greatly benefit mankind.

To say the simplest, it is Dongdong with zero resistance. At present, only certain materials can exhibit a property under certain conditions (generally low temperatures).

A superconductor is a conductor with a very small resistance, so small that it is close to zero.

It can be understood as a super conductive conductor with almost zero resistance, and then it is generally no resistance.

Simply put, it is a conductor without resistanceThere is no loss in the conduction of electric current in superconductors, and there is no heating phenomenon of conductors passing through the current. If the conductor forms a loop, the current will be present in it forever without attenuation.

Slippery that can't conduct electricity.

The upstairs is hilarious :

Superconductors are conductors with zero resistance at ultra-low temperatures (-145 degrees Celsius to -272 degrees Celsius) and are still under research.

The realization of superconductors means that the energy will not be lost due to resistance during transmission, and the waste of electrical energy can be reduced.

The complete diamagnetism of superconductors will also bring great benefits to human beings, such as the manufacture of superconducting maglev trains, maglev aircraft, maglev earth satellites, etc., as well as the production of high-precision instruments and equipment such as particle accelerators and particle detectors.

Superconductors, also known as superconducting materials, refer to conductors with zero resistance at a certain temperature. In the experiment, if the measured value of the conductor resistance is less than 10-25, the resistance can be considered to be zero. The basic properties that superconductors have:

Full Electrical Conductivity:

In the superconducting state of a superconductor, electric current can flow without resistance inside it. Means that in the superconducting state, the superconductor can have zero resistance. Usually the current encounters some resistance during the transmission process, resulting in energy loss and heat generation.

However, the special properties of superconductors allow electric current to flow in them without energy loss, and this current is called superflow.

Fully diamagnetic:

Superconductors exhibit complete diamagnetism in the superconducting state, i.e., they have a repulsive effect on the external magnetic field. When a superconductor is in a superconducting state, it repels the magnetic field and excludes it completely from its interior. This phenomenon is called the Meissner effect.

Therefore, in the superconducting state, there will be no magnetic field inside the superconductor.

Flux quantization:

When a magnetic field passes through a superconducting loop, it is broken down into a series of discrete values called magnetic flux quanta. A magnetic flux quantum is a fixed unit, determined by a natural constant, denoted as , and the size of each magnetic flux quantum is about tesla·square meters.

Applications of Superconductors:

Superconducting power generation:

Superconductors can be used to make highly efficient generators and power generation coils for large-scale power generation. Superconducting power generation systems have the advantages of high energy transmission efficiency and zero energy loss.

Superconducting Transmission:

Due to the resistance-free current transmission characteristics of superconductors, superconducting transmission lines can achieve high current density and long-distance transmission, reducing power losses and line costs.

Superconducting energy storage:

Superconductors can be used to create high-energy-density superconducting energy storage devices that store and release large amounts of electrical energy to cope with peak load demand and grid stability.

This substance also conducts heat easily. Generally, metals are conductors.

A superconductor is a conductor that has zero resistance at a certain temperature. In experiments, if the measured value of the conductor resistance is less than 10-25, the resistance can be considered to be zero. Superconductors not only have zero resistance, but another important feature is that they are completely diamagnetic.

Superconductors were first discovered in 1911, the year Dutch scientist Heike Kamerlingh Onnes and others discovered that at extremely low temperatures, the resistance of mercury disappears and it becomes superconductive. Since then, the research on superconductors has been deepened, on the one hand, a variety of superconducting materials with practical potential have been discovered, and on the other hand, the research on superconductivity mechanism has also made some progress.
