A-LEVEL Physics: 5.2.3: Superconductivity (SaveMyExams)

Question 1

how can you lower the resistivity of a material?

Answer 1

decreasing temperature

Question 2

if a material is cooled below the ___ ___, its resistivity drops to ~0Ωm. it is now a…

Answer 2

critical temperature. superconductor

Question 3

superconductor:

Answer 3

material with no resistance below its critical temperature

Question 4

critical temperature:

Answer 4

the temperature at which a material becomes a superconductor

Question 5

why are superconductors useful for applications that require lots of electrical energy?

Answer 5

bc have virtually no resistivity, so no electrical energy is dissipated as thermal energy to the surroundings. efficient

Question 6

Due to having Virtually No Resistivity, Superconductors are Useful for: (2)

bc superconductors have virtually no resistivity, they are useful for: (2)

Answer 6

-strong magnetic fields

-reduction of energy loss/dissipation
