Question

materials whose resistivity suddenly becomes..... at a particular critical temperature is called as........

Answer 1

Answer:

1.Zero

1.Zero2.Super conductors

hope it helps....

Answer 2

Answer:

Any material exhibiting these properties is a superconductor. Unlike an ordinary metallic conductor, whose resistance decreases gradually as its temperature is lowered even down to near absolute zero, a superconductor has a characteristic critical temperature below which the resistance drops abruptly to zero
