WebApr 9, 2024 · The output characteristics of BJT can be divided into three areas – cut-off, saturation and active region. In the cut-off region both collector-base and emitter-base pn-junctions are reverse-biased – transistor is off. In the active region , base-collector pn-junction is reverse-biased, and base-emitter – forward-biased. Webmore. We have studied in the previous video that increasing the external voltage across the PN junction will not increase the current across it, it will only only produce the same number of charge carrier but number of charge carrier produced remain same. We know current is number of charges per unit time. Thus number of electrons diffusing ...
