Challenge Problems
Push your limits with challenges.
Question 1
Calculate the current through a BJT if the base current is 20µA and the collector current is 100µA. What is the total current?
💡 Hint: Remember to add the base and collector currents.
Question 2
Discuss the impact on a BJT's performance if the base doping concentration is significantly increased. What would happen to the current flow?
💡 Hint: Consider how doping affects charge-carrier dynamics.
