Question:
In an insulator, band gap is of the order of
In an insulator, band gap is of the order of
Show Hint
Larger band gap $\Rightarrow$ poor conductivity (insulator behavior).
Updated On: May 1, 2026
- $0.1$ eV
- $1$ eV
- $5$ eV
- $100$ eV
- $1$ MeV
Show Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Concept:
Energy band gap classification:
• Conductors: $\approx 0$ eV
• Semiconductors: $\approx 1$ eV
• Insulators: $\approx 3 - 10$ eV
Step 1: Identify correct range.
Insulators have large band gap. \[ \text{Typical value} \approx 5 \text{ eV} \]
