Alright, envision you have a seriously awesome slide within the playground. Normally, when 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 where there's no friction whatsoever! You'll go down super fast without something slowing you down. That's style of like what transpires within a superconductor.
In a regular wire, when electrical power flows, it faces some resistance, which can be like friction for the electrical recent. This resistance helps make the wire warmth up and wastes some Strength.
But inside a superconductor, there is not any resistance in any way! The electricity can stream flawlessly with none Strength loss, similar to you taking place that magic slide super rapid. Nonetheless, to help make this take place, superconductors should be really, incredibly cold, colder than ice read here cream, even colder than nearly anything inside your freezer!
