Challenge Problems
Push your limits with challenges.
Question 1
A transistor has a collector current of 50 mA and Ξ² of 200. How does changing Ξ² affect the base current and what practical implications does this have for circuit design?
π‘ Hint: Consider how variations in current gain affect the transistor's overall performance.
Question 2
If a circuit is designed with V_BE = 0.7V and V_CB = 2.5V, analyze how these voltages might lead to changes in transistor behavior across different applications.
π‘ Hint: Think about the balance between forward and reverse biases.
