NEET Physics (general) MCQ Question
Type: MCQ-fact-Hard-Class 12
Which of the following statements accurately describes the energy gap in insulators?
A
The energy gap E_g is greater than 3 eV, preventing electrical conduction.
B
The energy gap E_g is less than 1 eV, allowing for high electrical conductivity.
C
The energy gap E_g is exactly 3 eV, enabling some conduction.
D
The energy gap E_g is variable and depends on temperature for conduction.
Correct Answer
Option A
Detailed Explanation
In insulators, the energy gap E_g is greater than 3 eV, which means there are no electrons in the conduction band, making electrical conduction impossible.
