The forbidden energy band gap in conductors, semi conductors and insulators are $E_{G1}, E_{G2}$ and $E_{G3}$ respectively. The relation among them is
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → $E_{G1}<E_{G2}<E_{G3}$
for conductors, $E_{G1}≃0$
for semiconductors, $E_{G2}≃0.1eV-3eV$
for insulators, $E_{G3}≃>3eV$
$∴E_{G1}<E_{G2}<E_{G3}$
