Alright, imagine you do have a really great slide with the playground. Ordinarily, whenever you go down a slide, there is certainly some friction that slows you down a little bit. 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 should go down Tremendous quick with out anything slowing you down. Which is form of like what takes place inside a superconductor.
In a daily wire, when energy flows, it faces some resistance, and that is like friction for the electric current. This resistance will make the wire heat up and wastes some energy.
But in a very superconductor, there is no resistance at all! The electric power can movement beautifully with no energy reduction, identical to you going down that magic slide Tremendous fast. On the other hand, to produce this materialize, superconductors have to be incredibly, extremely cold, colder than ice product, even colder than something with view all your freezer!
