Q. The forbidden energy band gap in conductors, semiconductors and insulators are $EG_{1},\ EG_{2}$ and $EG_{3}$ respectively. The relation them is
A) $EG_{1} = EG_{2} = EG_{3}$
B) $EG_{1} < EG_{2} < EG_{3}$
C) $EG_{1} > EG_{2} > EG_{3}$
D) $EG_{1} < EG_{2} > EG_{3}$
Explanation
(b) In insulators, the forbidden energy gap is very large, in case of semiconductor it is moderate and in conductors the energy gap is zero
