Question

In semiconductors at a room temperature(a) the conduction band is completely empty(b) the valence band is partially empty and the conduction band is partially filled(c) the valence band is completely filled and the conduction band is partially filled(d) the valence band is completely filled

Answer 1

(b) is the correct answer

as in semiconductors even at room temperature electrons from the valence band could move to conduction band unlike insulators where at room temperature electrons are not able to jump from valence to conduction band.

hope it helps...
