The resistivity range for semiconductors in ohm-meter is
Correct answer: B. 10-6 to 101
- A. 10-2 to 102
- B. 10-6 to 101
- C. 106 to 108
- D. 10-8 to 108
Explanation
The correct answer is 10-6 to 101 ohm-meter, which is characteristic of semiconductors. Semiconductors have resistivity values that are between those of conductors (which have very low resistivity) and insulators (which have very high resistivity). Option A is incorrect because it suggests a range typical of conductive materials. Option C is incorrect because it represents the range of insulating materials. Option D is incorrect because it encompasses a wide range, including values for conductors, semiconductors, and insulators, which does not accurately represent semiconductors specifically.

About Physics of Solids
Solids are compared through crystal structure, amorphous arrangement, elasticity, plastic deformation, stress, strain and Young’s modulus. Electrical behavior depends on available charge carriers and band structure, so conductors, insulators and semiconductors must be distinguished from mechanical properties such as strength, stiffness and brittleness.
