Superconductors do exist, I don t know

BigBigEasy is right, superconductivity exists, you also said that it is the ideal power supply, when have you learned that the ideal power supply can be shorted with a wire, obviously, this is a theoretical problem, and, in theory, when have you ever seen an ideal wire with resistance, so this kind of theoretical or intuitive possible things may not necessarily exist in reality. Another point to note is that the current in the superconducting wire can be infinite in theory, and in reality, the current in the superconductor can also be increased to a large enough amount, because there is no resistance and no heat, of course, there will be no superconductor, and the wire composed of superconductors will not be burned out.

Voltage Resistance = Current.

Applicable only to pure resistive circuits

Superconductivity has no resistance, it's not a resistive circuit, and the formula doesn't apply, like electric motors, where electrical energy is converted not only into heat, but also into mechanical energy.

If the power supply used is not the ideal power supply, then use i=e (power electromotive force) r (battery internal resistance), then the result is a short-circuit current

Superconductor currents cannot be calculated using that formula.

By the way, as long as there is an electric current in the superconductor, then it will not disappear

Since the denominator (resistance) is close to 0 and the numerator (voltage) is certain, the result (current) of the two is infinite.

Finite size, like a large magnet (voltage) at one end, put some small iron filings on one side, assume that there is no resistance in the process of moving iron filings, but as long as the magnet is constant, there is a limit to the amount of iron filings that can be moved per unit of time, and physics is not calculated by formulas, formulas can only be established under certain conditions, and now the formula is not valid.

In the case of superconductivity, many physical formulas are no longer applicable, just like when the object reaches the speed of light, it is no longer possible to calculate ordinary physical formulas.

Superconductivity exists, but a power supply without internal resistance does not exist.

So there can still be an electric current.

You're the one that purely measures the short-circuit current.

Superconductors have no resistance, but power supplies do, so the current is limited and large.

No matter how superconductors are, they have resistance, they are not infinity, they have a colonization, and there are generally other formulas.

It can't be infinity. There is another theory of superconductivity.

Superconductivity can only be explained by quantum physics, not by general formulas.

What is called superconductor is as follows:

Superconductors, also known as superconducting materials, refer to conductors with 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. 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 the magnetic field passes through the superconducting loop, it is broken down into a series of discrete values called magnetic flux particles. 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 high-efficiency 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 power transmission: Due to the resistance-free hand current transmission characteristics of superconductors, superconducting transmission lines can achieve high current density and long-distance transmission, reducing power loss 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.

Superconducting Computers:

Taking advantage of the low energy consumption and high computing speed of superconductors, superconducting quantum computers and superconducting logic circuits can be developed to achieve ultra-high-speed computing and data processing.

Superconducting antennas: Superconductors have low losses in the RF and microwave bands and can be used to create high-performance antennas and receivers for pure and radio applications.

Superconducting Microwave Devices:

Devices such as superconducting microwave filters, resonators, and amplifiers are used in wireless communications, radar systems, and RF electronics to provide higher performance and enhanced signal processing.

Compendium of Chinese Dictionaries Superconductors

It refers to the fact that at extremely low temperatures, some metals, alloys, metal compounds, etc. will become non-resistant. When an electric current passes through a superconductor, the current is not dissipated, and if it is placed in a magnetic field, there is no magnetic field in the body at all.

The current research on superconductors in the field of sentence physics is in the ascendant.

Chinese Dictionary Revised Version Superconductor Rotten example 1 At extremely low temperatures, many metals, alloys, and composites will become resistance-free. If there is current, the current will not be dissipated; If it is placed in a magnetic field, there is no magnetic field in its body at all. Objects in this state are called superconductors.
