Question

Write a short note on superconductivity. List some applications of superconductors.

Answer 1

Superconductivity :-
Superconductivity is define as the by which it acquires electric current with practically no resistance .Only material acts like a superconductor when the Low temperature is there.

The equation for superconductive state to it's Normal state :-
Refer to the Attachment.

 $\frac{H_{c}T }{H_{0}T } = 1- \frac{T^2 }{T^2_{c}}$


Applications of Superconductivity :-

There are lots of Applications of Superconductivity 

 (i)In radio-frequency amplifiers (FM)
(ii) Detector :- sensitive visible-light and infrared detectors
(iii) Transmitting signals :- wireless transmitting antennas
(iv) Underwater detector :- used to detect submarines and underwater mines etc.
(v) Medical application :- Avail magnets for MRI (Magnetic Resonance Imaging)
(vi) In research and Industries :- Magnet for material separation as well as demonstration also used as gyroscope in earth orbiting satellite .

Uses :-

(i) Used in bullet trains .
(ii)Used in hyper loops as a power cables 
(iii)ultra high speed computer chip.
(iv) In digital memory chip.



Hope it Helps :-) 

Answer 2

HEY MATE HERE IS YOUR ANSWER:-

certain metals and alloys lose their resistance considerably below a certain low temperature called critical temperature or transition temperature. such substances are called superconductors and this phenomenon is called super conductivity.

APPLICATIONS:-
1.THEY CAN BE USED TO TRANSMIT ELECTRICAL POWER WITHOUT ANY LOSS OF ELECTRIC ENERGY.
2.THEY CAN BE USED TO PRODUCE VERY HIGH MAGNETIC FIELD.
