Question

With decrease in temperature, the resistivity of a conductor :
(A) increases
(B) decreases
(C) may increases or decreases
(D) does not change
​

Answer 1

Explanation:

When the temperature increases the vibrations of the metal ions in the lattice structure increases. ... This means that the resistivity of the metal increases and thus current flow in the metal is decreased. The resistivity increases means that the conductivity of the material decreases.

Answer 2

With decrease in temperature, the resistivity of a conductor Increases
