copper
Meissner Effect
uperconductors expel magnetic fields from their interior when they transition into the superconducting state, causing them to repel magnets and allowing for magnetic levitation.
which liquid is use for superconductor
liquid helim
resisitance of semi conductor on heating
decrease
electric conduction in semi conductor takes place in both electron and holes
at absolute zero the electric resistance in semi conductor is
infinite
control rod in nuclear reactor is made of
