Assertion: The resistivity of a semi-conductor increases with temperture.
Reason: the atoms of semi conductor vibrate with large amplitude at higher temperture thereby increasing its resistivity.
Reason: the atoms of semi conductor vibrate with large amplitude at higher temperture thereby increasing its resistivity.
View answer and explanation
Correct option: D
Assertion and reason both are false
Both statements are false. The resistivity of a semiconductor decreases with increasing temperature due to increased charge carriers.
