← ScienceWhich outcome results when a diode's reverse bias increases?
A)Depletion region width expands✓
B)Forward current flow increases
C)Minority carrier injection increases
D)Diode heats excessively fast
💡 Explanation
An increased reverse bias widens the depletion region due to increased electric field strength drawing mobile carriers away from the junction zone - the Charge Depletion mechanism. Therefore, the depletion region widens, rather than forward current increasing, because the junction becomes more insulating.
