Assertion: The resistivity of a semiconductor increases with temperature.
Reason: The atoms of a semiconductor vibrate with larger amplitude at higher temperature therby increasing it resistivity.

A

If both the assertion and reason are true and reason is a true explanation of the assertion.

B

If both the assertion and reason are true but the reason is not the correct explanation of assertion.

C

If the assertion and reason are false

D

If both the assertion and reason are false.

Text Solution

Verified by Experts

The correct Answer is:
D
(d) Resistivity of a semiconductor decreases with the temperature. The atoms of a semiconductor vibrate with larger ampliutes at higher temperatures thereby increasing its conductivity not resistivity.
