Challenge Problems
Push your limits with advanced challenges
If the base-emitter junction's forward bias voltage is increased, predict the changes in the terminal currents of the BJT and explain why these changes occur.
💡 Hint: Consider the role of voltage in enhancing carrier movement.
Imagine a scenario where both junctions of a BJT are placed in close proximity. Describe the impact on minority carrier distribution and resultant current contributions.
💡 Hint: Focus on how junction proximity alters carrier mobility.
