Electronic Devices Question 41

Question: The forbidden energy band gap in conductors, semiconductors and insulators are EG1,EG2 and EG3 respectively. The relation among them is

[MP PMT 1994; RPMT 1997]

Options:

A) EG1=EG2=EG3

B) EG1<EG2<EG3

C) EG1>EG2>EG3

D) EG1<EG2>EG3

Show Answer

Answer:

Correct Answer: B

Solution:

In insulators, the forbidden energy gap is very large, in case of semiconductor it is moderate and in conductors the energy gap is zero.
