Question 1
What happens to electrons in a BJT under strong reverse bias?
- They are repelled
- They flow freely
- They are collected efficiently
💡 Hint: Consider the movement direction of charge carriers.
Question 2
Is it true that minority carriers have a higher concentration than majority carriers in a semiconductor?
- True
- False
💡 Hint: Think about the definitions of minority and majority carriers.

Challenge Problems
Push your limits with challenges.
Question 1
Given a BJT with varying reverse bias voltages, graph how the collector current would increase or decrease. Explain your reasoning.
💡 Hint: Consider the relationship between voltage and current flow.
Question 2
Explain the changes in the minority carrier profile if the BJT was in forward-bias conditions instead of reverse bias.
💡 Hint: Think about how forward bias conditions alter carrier dynamics.
