Superconductors

Definition

    - these are high temperature conductors with a resitivity of 0 at low temperatures
    - According to Websters - 
             -"A synthetic material thathas very low or no electrical resistance. Such experimental materials are beinginvestigated in laboratories to see if they can be created at near room temperatures. Ifsuch a superconductor can be found, electrical transmission lines with no little orno resistance may be built, thus conserving energy usually lost in transmission.Superconductors could also have uses in computer chips, solid state devices andelectrical motors or generators"

Applications of such a thing:

   - magnetically leviated trains
   - high-voltage transmission lines with no electrical resistance and high speed
   - miniaturized electronic computer chips

History of Superconductivity

    - Discover in 1911 by Dutch Physicisit 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 excluds magnetic fields from its interior
    - There is a loss of resistance at temperatures below the critical  temperature
