(v) If conduction band is not completely filled or it lies very close to a higher unoccupied band, then electrons can flow easily under an electric field thereby showing conductivity. (vi) In case of insulators, the gap between valence band and conduction band is too large, so electrons cannot jump from valence band to conduction band and very small conductivity is observed.
