Transfer characterstics [output voltage `(V_(o))` vs. input voltage `(V_(i))`] for a base biased transistor in `CE` configuration is as shown in the figure. For using transfor as a which, it is used

A. ln region I
B. Both in region (I) and (III)
C. In region III
D. In region II

A. ln region I
B. Both in region (I) and (III)
C. In region III
D. In region II
Correct Answer – B
For using the transistor as a switch, it is used in region I and region III where we get ON and OFF operations for the switch. Region II is the active region , where it is used as an amplifier.
