If the forward voltage in a p-n junction diode is increased, the width of the depletion region:
Decreases
In a p-n junction diode, the depletion region is formed due to the diffusion of charge carriers, creating an electric field.
- In forward bias, applying a positive voltage reduces the built-in potential, allowing more charge carriers to flow.
- As a result, the depletion width decreases because the external voltage reduces the barrier for charge movement.
Thus, the correct answer is (b).
