Challenge Problems

Push your limits with challenges.

Question 1

A transistor has a collector current of 50 mA and β of 200. How does changing β affect the base current and what practical implications does this have for circuit design?

💡 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.

💡 Hint: Think about the balance between forward and reverse biases.
