← ScienceWhich outcome reduces current flow when applying reverse bias?
A)Depletion region widens near junction✓
B)Electron-hole pairs spontaneously generate
C)Minority carriers begin rapid diffusion
D)Drift velocity reaches saturation limit
💡 Explanation
The depletion region widening prevents current flow because it increases the potential barrier hindering carrier movement during thermal diffusion and drift; therefore current decreases near the junction rather than generating hole pairs or saturating drift velocity.
