Question 1.
What is the main purpose of the base current in a BJT?
Show hintHide hint
Think about how BJTs can amplify signals.
Question 2.
Define collector current in your own words.
Show hintHide hint
Focus on the injection from the emitter when answering.
3Question 3.
What does I_B depend on primarily?
- Temperature
- Saturation Current
- V_BE
Show hintHide hint
Recall how voltage influences base current in your studies.
4Question 4.
Collector current has a direct linear relationship with?
- True
- False
Show hintHide hint
Think about the behavior of currents in a diode versus a transistor.
Question 5.
A BJT transistor has a saturation current of 10nA. Calculate the collector current when V_BE = 0.7V and β = 100. Assume full saturation.
Show hintHide hint
Break it into steps to compute I_B and then I_C using the relationships you've learned.
Question 6.
Explain how increasing the emitter-base voltage impacts both the base and collector currents quantitatively and qualitatively.
Show hintHide hint
Focus on the exponential relationships introduced.
