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.

πŸ’‘ 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

πŸ’‘ 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.

πŸ’‘ 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.

πŸ’‘ Hint: Use R_E wisely, as it’s key to ensuring stability!
