Question 1
What happens when the input voltage is increased too much in a common emitter configuration?
- Collector current decreases
- Output becomes clipped
- No change occurs
💡 Hint: Consider the limits of transistor operation.
Question 2
True or False: The Q-point can vary without affecting the amplifier's performance.
- True
- False
💡 Hint: Think about the importance of consistency in amplification.

Challenge Problems
Push your limits with challenges.
Question 1
A BJT is analogous to a narrow highway leading to a crowded city center. Given that the input voltage is the amount of cars (current) you allow on the highway, what can happen to the output (traffic flow) if there are too many cars? Explain in context to the BJT's output.
💡 Hint: Use the traffic analogy to consider current flow limitations.
Question 2
If an increase in temperature causes a BJT to exceed the thermal limits affecting the Q-point, how does this impact amplification? Provide an example scenario.
💡 Hint: Think about how conditions outside normal operating range affect device performance.
