Question

state the effect that forward bias has on the depletion layer width, junction resistance and current characteristic of a PN Junction

Answer 1

Answer:

If a suitable positive voltage (forward bias) is applied between the two ends of the PN junction, it can supply free electrons and holes with the extra energy they require to cross the junction as the width of the depletion layer around the PN junction is decreased.

Answer 2

Answer:

Explanation:

It is also to be noted that after completion of reverse biased depletion layer there is no more drift of charge carriers (electrons and holes) through the junction as the potential barrier opposes the applied voltage
