Alright, consider you've got a definitely awesome slide on the playground. Normally, when you go down a slide, there is some friction that slows you down somewhat. Friction is such as tough areas of the slide that make you go slower.
Now, image a magic slide exactly where there's no friction in any respect! You'll go down super 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 get in touch for the electric current. This resistance would make the wire heat up and wastes some energy.
But in a very superconductor, there is no resistance in the slightest degree! The electric power can movement beautifully with no energy reduction, just like you happening that magic slide Tremendous quick. Having said that, to produce this materialize, superconductors have to be pretty, extremely cold, colder than ice product, even colder than something with your freezer!
