Alright, visualize you've got a definitely cool slide on the playground. Commonly, once you go down a slide, you will find some friction that slows you down somewhat. Friction is like the tough aspects of the slide which make you go slower.
Now, image a magic slide in which there is no friction in the least! You would go down Tremendous rapidly with no everything slowing you down. That's kind of like what comes about in the superconductor.
In a regular wire, when electrical energy flows, it faces some read here resistance, which is like friction for the electrical existing. This resistance tends to make the wire warmth up and wastes some Vitality.
But in a superconductor, there isn't any resistance in any respect! The energy can circulation completely with no Power decline, much like you going down that magic slide super speedy. However, to produce this take place, superconductors need to be very, very chilly, colder than ice cream, even colder than nearly anything in your freezer!
