Question 1

What happens to electrons in a BJT under strong reverse bias?

  • They are repelled
  • They flow freely
  • They are collected efficiently

πŸ’‘ 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

πŸ’‘ 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.

πŸ’‘ 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.

πŸ’‘ Hint: Think about how forward bias conditions alter carrier dynamics.
