Alright, consider you've got a definitely awesome 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 at all! You'd go down Tremendous speedy devoid of nearly anything slowing you read here down. That is type of like what happens inside of a 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 isn't any resistance in any way! The electricity can stream properly with none Strength decline, similar to you taking place that magic slide super rapid. Nevertheless, to help make this take place, superconductors should be extremely, incredibly chilly, colder than ice cream, even colder than nearly anything inside your freezer!
