Alright, visualize you've got a definitely cool slide on the playground. Normally, after 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's no friction in any respect! You should go down Tremendous quickly without having anything at all slowing you down. That's style of like what transpires in the superconductor.
In a regular wire, when electrical energy flows, it faces some read here resistance, that is like friction for the electric present-day. This resistance makes the wire heat up and wastes some Power.
But in a superconductor, there isn't any resistance in any respect! The electricity can stream properly with none Vitality decline, similar to you taking place that magic slide super rapidly. Nevertheless, for making this take place, superconductors should be extremely, incredibly chilly, colder than ice cream, even colder than everything in your freezer!
