Alright, think about you have a genuinely neat slide at the playground. Generally, any time you go down a slide, there is some friction that slows you down somewhat. Friction is similar to the tough areas of the slide that make you go slower.
Now, picture a magic slide exactly where there is not any friction in any respect! You would probably go down super quickly without having something slowing you down. Which is form of like what takes get in touch place within a superconductor.
In a regular wire, when energy flows, it faces some resistance, and that is like friction 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 at all! 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 happen, superconductors have to be pretty, really chilly, colder than ice product, even colder than something as part of your freezer!
