- \(>10~\Omega/cm^3\)
- \(10^{-6}~\Omega/cm^3\)
- \(10^{-16}~\Omega/cm^3\)
- \(10^{-14}~\Omega/cm^3\)
Show Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Concept:
Semiconductors possess resistivity values intermediate between conductors and insulators.
Their resistance is much larger than metals and much smaller than insulators.
Step 1: Compare typical values.
Conductors: \[ 10^{-6}\Omega cm \] Semiconductors: \[ 10^{-2}\Omega cm \text{ to } 10^{9}\Omega cm \] Insulators: \[ >10^{14}\Omega cm. \]
Step 2: Choose the appropriate range.
Among the given choices, the semiconductor value corresponds to \[ \boxed{>10~\Omega/cm^3}. \]
