In forward bias the width of depletion layer in a p-n junction diode (a) increases (b) decreases (c) remains constant (d) first increases then decreases

Answer: (b). Forward bias lowers the barrier and pushes majority carriers into the junction region. Uncovered ions get neutralised, so the depletion layer width decreases. So the answer is (b).

P-N Junction Diode

In forward bias the width of depletion layer in a $p\text{-}n$ junction diode

Show answer and solution

Answer: (b)

Forward bias lowers the barrier and pushes majority carriers into the junction region.
Uncovered ions get neutralised, so the depletion layer width decreases.
So the answer is (b).
