Question

if the forward voltage in a diode is increased the length of the depletion layer will

Answer 1

I think it Will decreases

Answer 2

If the forward voltage in a diode is increased the length of the depletion layer will DECREASE.

◆The concentration difference of electrons and holes on either sides , p and n of PN JUNCTION diode establishes a density difference across the junction.

◆As a result holes diffuse from P to N that is from higher concentration to Lower concentration and similarly electrons from N to P regions. They RECOMBINE as the reach there.

◆This recombination of electrons and holes leads to the formation of a region at junction called DEPLETION LAYER.

◆As the forward voltage increases , depletion layer decreases as there would be less RECOMBINING of majority carriers after diffusion.

◆In reverse voltage , depletion layer increases.
