Question

Identical piece of Ge and Cu are taken and cooled, then (A) Resistivity of both increases (B) Resistivity of both decreases (C) Resistivity of Cu increases and Ge decreases (D) Resistivity of Cu decreases and Ge increases

Tardigrade Admin · Accepted Answer

Ge is a semiconductor so its resistivity decreases with increase in temperature.

Q. Identical piece of $G e$ and $C u$ are taken and cooled, then

Resistivity of both increases

Resistivity of both decreases

Resistivity of Cu increases and Ge decreases

Resistivity of Cu decreases and Ge increases

$G e$ is a semiconductor so its resistivity decreases with increase in temperature.
