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

Answer: (a). Forward bias opposes the barrier field and pushes majority carriers toward the junction. So the barrier voltage falls, the depletion layer narrows and current flows. So the answer is (a) width of depletion layer decreases.

P-N Junction Diode

If p-n junction diode is forward biased then

Show answer and solution

Answer: (a)

Forward bias opposes the barrier field and pushes majority carriers toward the junction.
So the barrier voltage falls, the depletion layer narrows and current flows.
So the answer is (a) width of depletion layer decreases.
