Figure shows the transfer characteristics of a base biased CE transistor. Which of the following statements are true ?A) At V1 = 0.4 V transistor is in active stateB) At V1 =1V it can be used as an amplifierC) At V1 = 0.5 V , It can be used as a switch turned offD) At V1 = 2.5 V , it can be used as a switch turned on

From the given transfer characteristics of a base biased common emitter transistor, we note thatii) When V1 = 1V ( which is in between 0.6V to 2.V), the transistor circuit is in active state and it used as an amplifieriii) When V1 = 0.5V there is no collector current , The transistor is in cut-off state. The transistor circuit can be used as a switch turned offiv) When V1 = 2.5V the collector current becomes maximum and transistor is in saturation and can be used as switch turned on state

Detailed Solution

From the given transfer characteristics of a base biased common emitter transistor, we note that
ii) When V₁ = 1V ( which is in between 0.6V to 2.V), the transistor circuit is in active state and it used as an amplifier
iii) When V₁ = 0.5V there is no collector current , The transistor is in cut-off state. The transistor circuit can be used as a switch turned off
iv) When V₁ = 2.5V the collector current becomes maximum and transistor is in saturation and can be used as switch turned on state
