Question
In the circuit shown, the PNP transistor has and . Assume that . For to be , the value of (in ) is _______

Correct answer
1.04 to 1.12
Solution
Given the PNP transistor circuit:
Since the emitter is at :
- (Emitter supply)
- (Collector voltage)
Since the emitter is at :
2.Calculate the base current :
The base is connected to ground through :3.Calculate the collector current :
4.Calculate for :
In this configuration, is the voltage across to ground:The value of is approximately , which falls within the range .Continue learning with Success Tracker
