Alright, envision you have a actually interesting slide at the playground. Typically, any time you go down a slide, there's some friction that slows you down a little. Friction is similar to the rough areas of the slide that make you go slower.
Now, picture a magic slide where there is not any friction whatsoever! You'll go down super fast without just about anything slowing you down. Which is sort of like what occurs in a superconductor.
In a daily wire, when electric power flows, it faces some resistance, that's like friction for the electric present-day. This resistance can make the wire heat up and wastes some Electrical power.
But in the superconductor, there's no resistance in the least! The electrical power can flow correctly without any Electrical power reduction, identical to you going down that magic slide Tremendous fast. On the other get in touch hand, to create this materialize, superconductors have to be incredibly, extremely cold, colder than ice product, even colder than anything with your freezer!
