    Transfer characteristics [output voltage \[({{V}_{0}})\] vs input voltage \[({{V}_{1}})\]] for a base biased transistor in CE configuration is as shown in the figure. For using transistor as a switch, it is used 

    A)  in region (III)

    B)       both in region (I) and (II) 

    C)         in region (II)    

    D)             in region (I)   

    Correct Answer: B

    Solution :

    [b] \[I\to ON\,\,\,\,II\to OFF\] In \[I{{I}^{nd}}\] state it is used as a amplifier it is active region.
