4 cards from this section. Quick, good the night before a test.
What is the definition of a BJT?
Recall the full form of BJT.
What does beta (β) represent in a BJT?
Think about how currents relate to each other in the transistor.
What does beta (β) in a BJT indicate?
Think about the relationship between base and collector currents.
True or False: In a BJT, the collector current is always greater than the base current.
Recall the definition of beta.
Design a circuit with an n-p-n transistor that operates in the active region with a base voltage of 1V and collector voltage of 10V. What resistor values are needed to maintain appropriate biasing?
Remember to maintain the base-emitter forward-bias and collector-emitter reverse-bias conditions.
Suppose you have a BJT with a beta of 120 and a base current of 10µA. If you suddenly decrease the base current to 5µA, what effect does this have on collector current?
Think about how IC relates to changes in IB and their respective impacts.
