Assertion : In crystalline solids, the value of resistance is different in different directions.
Reason : Crystalline solids are isotropic in nature.

A

If both (A) and ( R) are correct and ( R) is the correct explanation of(A).

B

If both (A) and ( R) are correct, but ( R) is not the correct explanation of (A).

C

If (A) is correct, but ( R) is incorrect.

D

If both (A) and ( R) are incorrect.

Text Solution

Verified by Experts

The correct Answer is:
C
Crystalline solids are anisotropic in nature that is, some of their physical properties like electrical resistance show different values along different directions due to different arrangement of particles in different directions.
