Assertion :-(A) semiconductors are solids with conductivites in the intermediate range from`10^(-6)-10^(4) ohm ^(-1)m^(-1)`
Reason :-(R ) internmediate conductivity in semiconductor Is due to partially filled valence band .

A

If both assertion and reason and true and reason is the correct explanation of assertion.

B

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

C

If assertion is true but reason is false.

D

If both assertion and reason are false.

Text Solution

Verified by Experts

The correct Answer is:
C
Conductance of semiconductors lies between metals and insulators, i.e., in therange of `10^(-6)` to `10^(4)ohm^(-1)m^(-1)`
