SUPERCONDUCTIVITY is the ability
of certain materials to conduct electric current with no
resistance and extremely low losses. This ability to carry
large amounts of currents can be applied to electric power
devices such as motors and generators and to electricity
transmission in power lines. For example, superconductors
can carry as much as 100 times the electricity ordinary
copper or aluminium wires of same size.Scientists had been
intrigued with the concept of superconductivity since its
discovery in the early 1900’s, but the extreme low
temperature the phenomenon required was a barrier to
practical and low cost application. This all changed in 1986
when a new class of ceramic super conductors were discovered
that ‘SUPERCONDUCTED’ at higher temperatures. The science of
high temperature superconductivity (HTS) was born, and Along
with it came the prospect for an elegant technology that
promises to ‘supercharge’ the way energy is generated,
delivered and used. At the heart of high temperature
superconductivity lies a promise for the near future. A
promise for transmitting and using electricity with near
perfect efficiency and much higher capacity, besides all
this it also has a wide range of application like MRI
scanning, maglev trains etc. This seminar shall discuss on
the concepts of superconductivity, its classifications, its
various properties and its applications.
