If p-n junction diode is forward biased, then (a) electric conduction is not possible. (b) width of depletion layer decreases. (c) width of depletion layer increases. (d) barrier voltage increases.

Answer: (b). Forward bias reduces the barrier and pushes carriers into the depletion region. So the depletion layer becomes narrower and conduction takes place. So the answer is (b) width of depletion layer decreases.

P-N Junction Diode

If p-n junction diode is forward biased, then

Show answer and solution

Answer: (b)

Forward bias reduces the barrier and pushes carriers into the depletion region.
So the depletion layer becomes narrower and conduction takes place.
So the answer is (b) width of depletion layer decreases.
