In the figure shows the transfer characteristics

Question:

In the figure shows the transfer characteristics of a base biased CE transistor. Which of the following statements are true?

(a) At Vi = 0.4V, transistor is in active state

(b) At Vi = 1V, it can be used as an amplifier

(c) At Vi = 0. .5V, it can be used as a switch turned off

(d) At Vi = 2.5V, it can be used as a switch turned on

 

Solution:

(b) At Vi = 1V, it can be used as an amplifier
