Decreases
Increases
First increases and then decreases
Remains constant
Answer is Right!
Answer is Wrong!
The correct answer is A. Decreases.
Semiconductors are materials that have electrical conductivity between that of a conductor and an insulator. The conductivity of a semiconductor increases with temperature, which means that the resistance decreases. This is because the increase in temperature causes the electrons to move more freely, which allows them to carry more current.
Option B is incorrect because the resistance of semiconductors decreases with temperature. Option C is incorrect because the resistance of semiconductors does not first increase and then decrease with temperature. Option D is incorrect because the resistance of semiconductors does not remain constant with temperature.
