Question 1
In which mode does a BJT behave like an open switch?
- Saturation
- Active
- Cutoff
- Reverse Active
💡 Hint: Consider which mode prevents current flow.
Question 2
True or False: In the saturation region, the collector current is primarily determined by the base current.
- True
- False
💡 Hint: Think about what happens when the transistor is fully on.

Challenge Problems
Push your limits with challenges.
Question 1
Consider a silicon BJT with a collector current (IC) of 10mA and a beta (β) of 50. Calculate the base current (IB) in the active region.
💡 Hint: Recall the current gain relationship.
Question 2
A BJT is biased such that its VBE is 0.7V and its IC reaches saturation. Discuss the implications for temperature effects on biasing.
💡 Hint: Analyze how temperature affects semiconductor behavior.
