The resistance of a semi-conductors
  • a)
    increases with increase of temperature
  • b)
    decreases with increase of temperature
  • c)
    does not charge with charge of temperature
  • d)
    first decreases and then increases with increase of temperature
Correct answer is option 'B'. Can you explain this answer?

The resistance of a semi-conductorsa)increases with increase of temper...
The resistivity of a semiconductor decreases with temperature. This is because of increasing temperature, the electrons in the valence band gain sufficient thermal energies to jump to the conduction band. As the number of electrons in the conduction band increases, so conductivity increases and resistivity decreases.
