Alright, consider you do have a really great slide with the playground. Commonly, whenever you go down a slide, there is certainly some friction that slows you down a tad. Friction is like the tough portions of the slide which make you go slower.
Now, image a magic slide in which there is no friction in any way! You should go down super quickly without having anything at all slowing you down. That's style of like what transpires in the superconductor.
In a regular wire, when electricity flows, it faces some resistance, which happens to be like friction for the electric current. This resistance will make the wire heat up and wastes some Power.
But inside of a superconductor, there is no resistance at all! The electric power can movement perfectly with get in touch no Power reduction, just like you happening that magic slide Tremendous quickly. Having said that, to generate this happen, superconductors have to be very, extremely chilly, colder than ice cream, even colder than just about anything within your freezer!
