Challenge Problems

Push your limits with challenges.

Question 1

Design a simple circuit using a BJT as a switch for an LED. Given a 12V supply and a base current of 2 mA, determine the maximum collector current you can expect if β = 120.

💡 Hint: Use the relationship between base current and collector current.

Question 2

Explain how the transfer characteristics of a BJT would change if it's overheating. What practical steps could you take in circuit design to handle this?

💡 Hint: Consider how temperature affects semiconductor behavior.
