Question 1.
What are the two primary junctions in a BJT?
Show hintHide hint
Think about their names; one is for the emitter and the other for the collector.
Question 2.
What happens during forward bias?
Show hintHide hint
Recall the effect of applying a positive voltage.
3Question 3.
What are the two junctions of a BJT?
- Base-emitter and base-collector
- Collector-emitter and base-collector
- Base-base and collector-collector
Show hintHide hint
Focus on the emitter and collector connections.
4Question 4.
In a BJT, which junction is typically forward biased during normal operation?
- True
- False
Show hintHide hint
Think about how BJTs are used in amplifiers.
Question 5.
A BJT operates with a base-emitter voltage of 0.7V while the base-collector is reverse biased. Calculate the expected base and collector currents given the forward currents are known.
Show hintHide hint
Use I_C = Beta * I_B, where Beta is the current gain.
Question 6.
If a BJT shows a collector current of 2 mA with a base current of 20 µA, determine the beta and provide its significance.
Show hintHide hint
Beta shows how much the base current is amplified to the collector current.
