Assertion : If the temperature of a semiconductor is increased, its resistance decreases.
Reason : The energy gap between conduction band and valence band in case of semiconductor is small.
Reason : The energy gap between conduction band and valence band in case of semiconductor is small.
View answer and explanation
Correct option: A
If both Assertion and Reason are true and the Reason is a correct explanation of the Assertion
Option A is correct because both the assertion and reason are true, and the reason correctly explains why resistance decreases with temperature in semiconductors.
