The transfer characteristics for a base biased transistor in CE configuration is as shown in the figure. For using transistor as an amplifier, it is used in:
Answer & explanation
Correct answer: option 2
In the given graph,
Region (I) – Cut off region
Region (II) – Active region
Region (III) – Saturation region
For using transistor as a switch it is used in cut off region or saturation region.
For using transistor as a amplifier it is used in active region.
