Vedclass · Answer

(A) In a $p-n$ junction diode,when a reverse bias is applied,the external electric field is in the same direction as the internal electric field of the depletion region. This causes the majority charge carriers to move away from the junction,thereby increasing the width of the depletion region. Conversely,in forward bias,the external field opposes the internal field,which reduces the width of the depletion region.
