Question 1.
What is the role of reverse bias in a BJT?
Show hintHide hint
Think about the flow direction of the current.
Question 2.
Define a minority carrier.
Show hintHide hint
Consider the types of charge carriers in a semiconductor.
3Question 3.
What happens to electrons in a BJT under strong reverse bias?
- They are repelled
- They flow freely
- They are collected efficiently
Show hintHide hint
Consider the movement direction of charge carriers.
4Question 4.
Is it true that minority carriers have a higher concentration than majority carriers in a semiconductor?
- True
- False
Show hintHide hint
Think about the definitions of minority and majority carriers.
Question 5.
Given a BJT with varying reverse bias voltages, graph how the collector current would increase or decrease. Explain your reasoning.
Show hintHide hint
Consider the relationship between voltage and current flow.
Question 6.
Explain the changes in the minority carrier profile if the BJT was in forward-bias conditions instead of reverse bias.
Show hintHide hint
Think about how forward bias conditions alter carrier dynamics.
