Show hintHide hint
What happens to a barrier when you add a positive voltage?
3Question 3.
What defines the active region of a BJT?
- Both junctions forward-biased
- One junction forward-biased
- Both junctions reverse-biased
Show hintHide hint
Think about how current flows through the BJT.
4Question 4.

- True
- False
Show hintHide hint
What relationship involves base, collector, and emitter currents?
Question 5.
Demonstrate how varying the base width influences the overall current gain β in a BJT.
Show hintHide hint
Consider how carrier density and lifetime are affected.
Question 6.
If you increase the reverse bias on the collector junction, how does this affect the collector current?
Show hintHide hint
Think about how the electric field affects carriers in the depletion region.
