3 cards from this section. Quick, good the night before a test.
Define what an n-p-n transistor is.
Remember the layers' arrangement.
What is the purpose of biasing in transistors?
Think about the importance of operational states.
Which of the following describes the function of the base in a transistor?
Think about the role of the small current in regulating larger currents.
True or False: In a p-n-p transistor, the collector current enters through the emitter.
Recall the current flow directions in n-p-n and p-n-p transistors.
Analyze a circuit containing a p-n-p transistor with an emitter voltage of +10V, a base voltage of +7V, and a collector voltage of +5V. What are the biases, and is the transistor in the active region?
Check if voltage conditions meet active region requirements.
Design an n-p-n transistor circuit using a supply voltage of 12V. If you have a resistor of 2kΩ in the base, determine the emitter current assuming beta = 100.
Begin with Ohm's Law to find base current first.
