In this case study, I will talk about how resistance is linked with superconductivity. I will also talk about the benefits and risks about superconducting materials and how superconductivity can enhance our daily life.
Superconductivity occurs in certain materials (metals and ceramic materials) at very low temperatures. When a material is superconductive, it has an electrical resistance of exactly ZERO. Because these superconducting materials have no electrical resistance, this means that the electrons can travel through them freely so energy isn’t lost through heat and are long-lasting materials. The electrical resistivity of a metallic conductor decreases gradually as the temperature is lowered, as the lower temperature makes it easier for the electrons to pair up with little or no resistance. In a superconductor, the resistance drops exactly to zero when the material is cooled below its critical temperature (the temperature at which electrical resistance is zero). So an electrical current flowing in a superconducting wire can persevere with NO power source.
