Vedclass · Answer

(B) In a common emitter transistor configuration,the transfer characteristic curve shows three distinct regions:$1$. Cutoff Region: When the input voltage $(V_{i})$ is low,the transistor is in the cutoff region,and the output voltage $(V_{o})$ is high (near $V_{CC}$). This corresponds to Region $I$.$2$. Active Region: As $(V_{i})$ increases,the transistor enters the active region where the output voltage $(V_{o})$ decreases linearly with $(V_{i})$. This corresponds to Region $II$.$3$. Saturation Region: When $(V_{i})$ is high,the transistor enters the saturation region,and the output voltage $(V_{o})$ becomes very low (near $0$). This corresponds to Region $III$.Therefore,the active,saturation,and cutoff regions are represented by $II, III$ and $I$ respectively.

The graph between the input voltage $(V_{i})$ and the output voltage $(V_{o})$ of a transistor connected in common emitter configuration is shown in the figure. The active,saturation and cutoff regions of the transistor are respectively
