A superconductor truly has zero electrical resistance.
It took scientists a half century to explain why, so this answer will omit the explanation of the effect.
Super cooled metals are good conductors because their super cooled properties allow them to conduct electric currents without resistance. This means no loss of energy.
No. A conductor is a good carrier of electricity or heat. A superconductor is a material in which the resistance to electrical flow is zero. Silver and copper are fairly good conductors, but some energy is lost.
Super-conductors have zero electrical resistance, allowing for highly efficient electricity transmission over long distances without energy loss. They can carry much higher amounts of electricity compared to traditional copper wires, potentially reducing the need for multiple transmission lines. Super-conductors also require less maintenance and have a smaller footprint, making them suitable for urban areas.
conductorCobalt is a metal. Metals are good conductors of heat and electricity.
super conductor
This seems like a question from an electrical course, and is probably best answered by your course materials.
It has no (zero) resistance - thus current flows without losses.
b
Metals are called poor conductors in comparison to materials such as copper and silver because they have higher resistivity, which hinders the flow of electrons or electricity through them. Poor conductors like iron and steel are less effective at conducting heat and electricity due to their atomic structure and electron mobility.
A superconductor has zero electrical resistivity below a specific temperature called the superconducting transition temperature.
Super conductors are conducting materials which below a specific temperature offer zero resistance to the conduction of current : Currently, superconductivity can only be achieved at extremely low temperatures.
