Question 1
What primarily defines the collector current in fixed bias arrangements?
- It is determined by the emitter resistor.
- It is dependent on the base current and B2.
- It is fixed regardless of conditions.
💡 Hint: Recall how fixed bias connects to the functioning of the transistor.
Question 2
True or False: Self-biasing circuits are more prone to instability compared to fixed bias.
- True
- False
💡 Hint: Differentiate the features of both bias types.

Challenge Problems
Push your limits with challenges.
Question 1
In a fixed bias circuit, if B2 varies from 100 to 200, calculate how much the collector current changes given an initial I_B of 1mA.
💡 Hint: Keep track of how B2 directly affects I_C.
Question 2
Design an optimal self-bias circuit that minimizes the impact of B2 variations in collector current. Explain your choice of resistors.
💡 Hint: Use R_E wisely, as it’s key to ensuring stability!
