Question 1
What is a primary disadvantage of fixed biasing?
- It is simple to implement
- It is sensitive to variations in beta
- It provides stable output
💡 Hint: Consider what happens during temperature changes.
Question 2
True or False: The voltage divider bias method is more stable than fixed bias due to feedback.
- True
- False
💡 Hint: Reflect on how feedback impacts stability.

Challenge Problems
Push your limits with challenges.
Question 1
In a fixed bias circuit with a BJT, the nominal beta is 150. What will happen to the collector current if the beta rises to 240 due to an increase in temperature?
💡 Hint: Use the relationship IC = βDC * IB to figure this out.
Question 2
Evaluate the potential effects on an amplifier's performance if the Q-point shifts to the cutoff region during a temperature test.
💡 Hint: Remember, cutoff means no current flow.
