Semiconductor Electronics question

2022 · Q131

NEETPhysicsSemiconductor ElectronicsMCQ+4 / −1

As the temperature increases, the electrical resistance

  1. A
    Increases for both conductors and semiconductors
  2. B
    Decreases for both conductors and semiconductors
  3. C
    Increases for conductors but decreases for semiconductors
  4. D
    Decreases for conductors but increases for semiconductors
View written solutionFree

Correct answer: C

As the temperature increases the resistivity of the conductor increases hence the electrical resistance increases. However for semiconductor the resistivity decreases with the temperature. Hence electrical resistance of semiconductor decreases.
