The surprising point that happens is the all electrical resistance fully disappears. That doesn"t just become really very really very very small. That literally becomes totally ZERO. As soon as the material is in that state of being, you can make a loop out of it and start some current flowing in the loop, and as long as you keep the superconductor cold enough, the current will store going around and also around and around and also around, v no loss, for MONTHS if you want to.It"s really surprising. 


You are watching: What is the surprising thing that happens in a superconductor


-- once you cool them, their electrical resistance decreases.-- If you do them also colder, your resistance to reduce more.-- If you make them even colder, your resistance decreases more.-- If you make them also colder, your resistance reduce more.Plz mark me brainliest!Hope this helps!

With virtually all building materials . . .-- as soon as you cool them, their electrical resistance decreases.-- If you do them also colder, your resistance reduce more.-- If you do them also colder, their resistance to reduce more.-- If you make them also colder, their resistance decreases more.-- If you save making them colder, their resistance keeps decreasing,but the never fully disappears, no matter exactly how cold you do them.But v a couple of surprising substances, dubbed "superconductors" . . .-- when you cool them, their electrical resistance decreases.-- If you do them even colder, your resistance reduce more.-- If you make them even colder, their resistance to reduce more.-- If you make them even colder, their resistance to reduce more.-- If you store making castle colder, then suddenly, at some magic temperature, their resistance completely disappears. The doesn"t just become small, and it doesn"t just become too tiny to measure. It becomes literally totally and absolutely ZERO. If you start a present flowing in a superconducting wire, because that example, you can attach the ends of the cable together, and also the current keeps flowing around and also around in it, because that months or years. As lengthy as you keep the loop cold enough, the present never decreases, becausethe superconducting cable has completely ZERO resistance.Did someone say "What"s this good for ? What deserve to you execute with it ?"1). Every CT-scan an equipment and every MRI device needs many powerful magnets to carry out its thing. They space all electromagnets, with coils of superconducting wire, fastened in containers full of liquid helium. Yes, it"s facility and expensive. But it transforms out come be much easier and cheaper than using regular electromagnets, through coils of consistent plainold copper wire, and the large power supplies that would be neededto store them going.2). Resistance in wire method that when existing flows with it,energy is lost. The lengthy cables indigenous the power-generating stationto your house have actually resistance, so energy is shed on the method from thegenerating station to your house. That lost energy is power that theelectric firm can"t sell, since they can"t supply it come customers.There are plans to construct superconducting cables to carry electric powerfrom the producer to the customers. The cables will be hole pipes,with fluid helium or liquid hydrogen inside to save them cold, and something top top the outside to insulate them from the warm outside.Yes, they"ll be complicated and expensive. But they"ll have ZEROresistance, so NO power will be shed on its way from the generating stations come the customers. The power service providers think they canbuild superconducting "transmission lines" the will price less thanthe energy that"s being shed now, with consistent cables.

With practically all substances . . .-- when you cool them, their electrical resistance decreases.-- If you do them also colder, your resistance reduce more.-- If you make them also colder, your resistance decreases more.-- If you make them even colder, your resistance decreases more.-- If you store making castle colder, their resistance keeps decreasing,but the never fully disappears, no matter how cold you do them.But through a couple of surprising substances, called "superconductors" . . .-- when you cool them, their electric resistance decreases.-- If you do them even colder, their resistance reduce more.-- If you make them even colder, your resistance reduce more.-- If you make them even colder, your resistance reduce more.-- If you store making castle colder, then suddenly, at some magic temperature, their resistance completely disappears. That doesn"t just come to be small, and also it doesn"t just end up being too little to measure. It becomes literally totally and absolutely ZERO. If you start a current flowing in a superconducting wire, for example, girlfriend can attach the ends of the wire together, and the present keeps flow around and also around in it, for months or years. As lengthy as you save the loop cold enough, the existing never decreases, becausethe superconducting cable has entirely ZERO resistance.Did someone say "What"s this an excellent for ? What deserve to you perform with it ?"1). Every CT-scan maker and every MRI an equipment needs many powerful magnets to do its thing. They space all electromagnets, through coils of superconducting wire, attached in containers complete of fluid helium. Yes, it"s complicated and expensive. Yet it turns out to it is in simpler and cheaper 보다 using continuous electromagnets, v coils of regular plainold copper wire, and also the large power provides that would be neededto store them going.2). Resistance in wire means that when existing flows with it,energy is lost. The lengthy cables from the power-generating stationto her house have actually resistance, so energy is lost on the way from thegenerating terminal to your house. The lost power is power that theelectric agency can"t sell, due to the fact that they can"t supply it to customers.There room plans to build superconducting cables to lug electric powerfrom the producers to the customers. The cables will certainly be hollow pipes,with liquid helium or fluid hydrogen inside to save them cold, and also something ~ above the outside to insulate them from the warmth outside.Yes, they"ll be complex and expensive. Yet they"ll have ZEROresistance, for this reason NO power will be shed on its means from the generating stations to the customers. The power providers think castle canbuild superconducting "transmission lines" that will cost less thanthe energy that"s being shed now, with continuous cables.
