Question 1.
What is the effect of applying forward bias to a p-n junction?
Show hintHide hint
Think of how it affects majority carriers.
Question 2.
Define reverse saturation current.
Show hintHide hint
Remember, 'minority carrier' is key.
3Question 3.
What characterizes forward bias in a p-n junction?
- Prevents current flow
- Allows current flow
- Has no effect
Show hintHide hint
Think about whether carriers can cross the junction.
4Question 4.
Is the reverse saturation current dependent on reverse bias voltage?
- True
- False
Show hintHide hint
Consider the characteristics of minority carriers.
Question 5.
Given a BJT with β = 200, if the base current is 10 μA, calculate the collector current.
Show hintHide hint
Use the formula involving β.
Question 6.
If the reverse bias voltage increases, explain how it affects the collector current and justify your answer using concepts from minority carrier dynamics.
Show hintHide hint
Think about how reverse bias affects carrier movement.
