What are the two types of current in a PNP transistor?
Think about how current enters and exits the transistor.
What condition must be fulfilled for the base-emitter junction of a PNP transistor?
Reverse this if thinking about NPN!
In a PNP transistor, the collector current flows:
Refer to how currents flow in PNP versus NPN.
True or False: In forward bias, the base voltage of a PNP transistor is higher than the emitter voltage.
Think about how we define forward bias.
Given a PNP transistor configuration with V_E = 10V, V_B = 9.3V, and V_C = -1V. Calculate the emitter current (I_E) if the base current (I_B) is 50 µA.
Use Kirchhoff’s law to sum the currents.
If a PNP transistor has a β of 150 and the collector current is 3 mA, what is the base current?
Remember β represents the current gain.
