Assertion : When the temperature of a semiconductor is increased, then its resistance decreases
Reason : The energy gap between conduction band and valence band is very small
Reason : The energy gap between conduction band and valence band is very small
View answer and explanation
Correct option: A
If both Assertion & reason are True & the reason is a correct explanation of the assertion
Option A (If both Assertion & reason are True & the reason is a correct explanation of the assertion) is correct because increasing temperature increases conductivity in semiconductors due to their small energy gap.
