Question 1.
What is a BJT?
Show hintHide hint
Remember 'Bipolar' relates to the two types of charge carriers.
Question 2.
What are minority carriers?
Show hintHide hint
Think of them as the 'underrepresented' charged particles in the semiconductor.
3Question 3.
What do BJTs use for charge transport?
- Only electrons
- Only holes
- Both electrons and holes
Show hintHide hint
Recall the term 'bipolar' in BJT.
4Question 4.
Is the collector current in a BJT directly dependent on base current?
- True
- False
Show hintHide hint
Think about how the base current affects overall current flow.
Question 5.
Calculate the collector current of an n-p-n BJT given the base current is 10 µA and β is 100.
