The forbidden energy band gap in conductors, semiconductors and insulators are `EG_(1), EG_(2)` and `EG_(3)` respectively. The relation among them is

A

`EG_(1)=EG_(2)=EG_(3)`

B

`EG_(1)ltEG_(2)ltEG_(3)`

C

`EG_(1)gtEG_(2)gtEG_(3)`

D

`EG_(1)ltEG_(2)gtEG_(3)`

Text Solution

Verified by Experts

The correct Answer is:
B
In insulators the forbidden energy gap is very large, in case of semiconductor if is moderate and in conductors.
