The forbidden energy gaps in conductors, semiconductors and insulators are $(E_g)_c, (E_g)_s$, and $(E_g)_I$ respectively. What is the relation among them?

$(E_g)_c < (E_g)_s< (E_g)_I$

The correct answer is Option (1) → $(E_g)_c < (E_g)_s< (E_g)_I$

The forbidden energy $(E_g)$ is the energy difference between the valence band and the conduction band in a material.

$(E_g)_c=0eV,(E_g)_s≃0.1eV-3.0eV$

$(E_g)_I≃5eV$
