Superconductors
Definition
- these are high temperature conductors with a resistivity of 0 at low temperatures
- According to Websters -
-"A synthetic material that have very low or no electrical resistance. Such experimental materials are being investigated in laboratories to see if they can be created at near room temperatures. If such a superconductor can be found, electrical transmission lines with no little or no resistance may be built, thus conserving energy usually lost in transmission.Superconductors could also have uses in computer chips, solid state devices and electrical motors or generators"
Applications of such a thing:
- magnetically levitated trains - high-voltage transmission lines with no electrical resistance and - high speed miniaturized electronic computer chips
History of Superconductivity
- Discover in 1911 by Dutch Physicist Heike Kamerlingh Onnes
- by the electrical resistance of mercury and other metals abruptly dropped to 0
Additional Facts
- Superconductors have a resistivity of 0 at low temperatures
- Indefinite Current Flow
- No Velocity
- Ceramics - a superconductor - able to superconduct at significantly higher temperatures (35K)
- superconducting material excludes magnetic fields from its interior - There is a loss of resistance at temperatures below the critical temperature
