Which of the following is a drawback to superconductors?
-They perform well only at very low temperatures.
-They are made from extremely expensive materials.
-They have very few uses.
-They are dangerous to use.
"They perform well only at very low temperatures."
Despite of advantages of Superconductors such as power and cost efficiency, these conductors have drawbacks. Semiconductors have restricted operation range of operating temperatures. They are required to work at very low temperatures.
