High conductivity materials in absolute temperatures

Click For Summary
SUMMARY

This discussion centers on the behavior of conductors when they reach their critical temperature, transitioning into superconductors. When a material is cooled to its critical temperature, it exhibits zero electrical resistance, allowing for uninterrupted current flow. However, once the temperature rises above this critical threshold, the material reverts to its normal conductive state, losing its superconductive properties. This phenomenon is crucial in applications such as magnetic levitation, exemplified by the Japanese maglev trains.

PREREQUISITES
  • Understanding of superconductivity principles
  • Knowledge of critical temperature in materials
  • Familiarity with electrical resistance concepts
  • Basic principles of electromagnetism
NEXT STEPS
  • Research the properties of superconductors and their critical temperatures
  • Explore applications of superconductivity in transportation, such as maglev trains

what happen to the conductor if it reaches the critical temperature where high conductivity and then back to the original case does it preserve by an amount of high conductivity or high conductivity disappear
just a question I'm engineering student electrical power department

Welcome to the PF.

For schoolwork-type questions, we require that you show some effort in answering your question. What have you read about superconductivity so far? What do you think will happen?
 
all what I know that when a material be cooled to the critical temperature its changes to super conductive material and this mean no resistance so when we put voltage source for a short time there's a current move for un certain time &this property happens because there's no collision between electrons and each double of electrons be attracted to each other &if we put a magnet over super conducting material it will be hanged over it &Japanese man benefited it in flying train
no more because we don't have interest with this science in egypt
