Question 1
What is the main function of the base in a BJT?
- To inject carriers
- To control the flow of current
- To collect current
💡 Hint: What is the layer's primary role?
Question 2
True or False: The emitter is reverse-biased in normal operation.

Challenge Problems
Push your limits with challenges.
Question 1
If the base-emitter voltage is increased, describe how the collector current will be affected in a BJT and why.
💡 Hint: Think about how the exponential relationship in the current equation relates to the applied voltage.
Question 2
Given a BJT with specific doping concentrations, calculate the expected multiplication factor for the carrier concentration in the base as the emitter junction is forward-biased.
💡 Hint: Relate this to how the forward bias influences carrier flow through the base region.
