Question 1
Easy
What does it mean when we say a junction is forward-biased?
💡 Hint: Think about which side is 'charged' more positively.
Question 2
Easy
Name the two types of carriers in a BJT.
💡 Hint: One type is present in p-type material while the other is in n-type material.

Question 1
Which condition allows current to flow from the emitter to the base in a BJT?
- Reverse Bias
- Forward Bias
- Cutoff
💡 Hint: Think about how the positive charge affects current flow.
Question 2
True or False: Minority carriers are present in larger concentrations than majority carriers in a BJT.
- True
- False
💡 Hint: Think about the definitions of majority vs. minority carriers.

Challenge Problems
Push your limits with challenges.
Question 1
If a BJT's base-emitter voltage is increased from 0.2V to 0.7V, describe the change in current flow in the junction.
💡 Hint: Recall how voltage and current are related in a diode.
Question 2
A BJT is operating at a temperature of 60°C and the intrinsic carrier concentration doubles. How does this impact the minority carrier concentration?
💡 Hint: Think about the impact of temperature on carrier dynamics.
