Alright, imagine there is a truly amazing slide for the playground. Ordinarily, once you go down a slide, you can find some friction that slows you down a tiny bit. Friction is just like the rough parts of the slide which make you go slower.
Now, photo a magic slide wherever there isn't any friction in the slightest degree! You would go down Tremendous rapidly with no everything slowing you down. That's kind of like what comes about in a very superconductor.
In an everyday wire, when electrical energy flows, it faces some resistance, that is like friction for the electrical existing. This resistance tends to make the wire warmth up and wastes some Vitality.
But inside a superconductor, there is view all not any resistance in any way! The electricity can stream flawlessly with none energy reduction, much like you taking place that magic slide super rapid. Nonetheless, to make this come about, superconductors should be quite, pretty cold, colder than ice cream, even colder than just about anything with your freezer!
