Question

What is total charge of depletion region in a diode in forward biasing?
​

Answer 1

Answer:

The remaining holes will cross the depletion region and gets attracted to negative terminal of battery or terminate at the negative terminal of the battery. Thus, the positive charge carriers that are crossing the depletion region carry the electric current from one point to another point in the p-n junction diode.

Answer 2

Answer:

the depletion region is so named because it is formed from a conducting region by removal of all free charge carrieries, leaving none to carry current.

the refion near the p-n junction whete the flow of chargr carriers is reduced over a given period and finally results in zero charge carriers
