Question
The transistor in the given circuit should always be in active region. Take , . The maximum value of in which can be used, is ______________.
Correct answer
22 to 23
Solution
To ensure the transistor remains in the active region, the collector-emitter voltage must be greater than or equal to the saturation voltage .
1.Calculate the base current ():
2.Calculate the collector current () in the active region:
3.Apply the active region condition ():
Thus, the maximum value of is approximately .Continue learning with Success Tracker
