If p-n junction diode is in forward bias then (a) width of depletion layer increases (b) electric conduction is not possible at all (c) barrier voltage increases (d) width of depletion layer decreases

Answer: (d). Forward bias lowers the barrier voltage and pushes majority carriers into the depletion region. So the depletion layer narrows and conduction occurs. So the answer is (d) width of depletion layer decreases.

P-N Junction Diode

If $p\text{-}n$ junction diode is in forward bias then

Show answer and solution

Answer: (d)

Forward bias lowers the barrier voltage and pushes majority carriers into the depletion region.
So the depletion layer narrows and conduction occurs.
So the answer is (d) width of depletion layer decreases.
