Question
In the circuit shown in the figure, the BJT has a current gain () of 50. For an emitter-base voltage , the emitter-collector voltage (in Volts) is ______.
Correct answer
2 to 2
Solution
Given: , .From the circuit diagram, we have a PNP transistor:
1.Emitter voltage .
2.Base voltage .
3.The base is connected to ground through a resistor. Thus, the base current is:
.4.Collector current .
5.Collector voltage is the voltage across the resistor:
.6.The emitter-collector voltage is:
.Verification of active region: . Since for a PNP transistor, it is in the active region.Continue learning with Success Tracker
