1
New cards

what are superconductors

when wires are cooled below their transitional/ critical temperatures, their resistance becomes 0 Ω.

2
New cards

what is the typical transitional temp for most metals

close to about 0K

3
New cards

why is it useful for certain materials to have higher transitional temps

it allows them to be cooled using liquid nitrogen instead of more expensive cooling methods

4
New cards

why are superconductors useful for carrying high currents

they eliminate resistance preventing power loss as heat
