If electrical conductivity increases with the increase of temperature of a substance, then it is a:
If electrical conductivity increases with the increase of temperature of a substance, then it is a:
Show Hint
Semiconductors like silicon and germanium become better conductors at higher temperatures due to increased charge carriers.

Hide Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
In semiconductors, the electrical conductivity increases as the temperature rises. This is because more electrons gain enough energy to jump from the valence band to the conduction band, leading to an increase in charge carriers.
In contrast, conductors experience a decrease in conductivity with an increase in temperature due to the scattering of charge carriers.
Thus, the correct answer is Semiconductor.
Thus, the correct answer is Semiconductor.
