Question 1.
What mode of operation is a BJT in when it amplifies signals?
Show hintHide hint
Think about the term that stands for amplification.
Question 2.
In which mode is the BJT turned off?
Show hintHide hint
Consider which mode prevents current from flowing.
3Question 3.
What operational mode allows BJTs to amplify signals?
- Cut-off
- Active
- Saturation
- Inverse Active
Show hintHide hint
Think of amplification.
4Question 4.
In which mode does the BJT operate as a switch?
- Active
- Cut-off
- Saturation
- Inverse Active
Show hintHide hint
Consider the maximum current flow.
Question 5.
A BJT is used in a circuit where it needs to switch loads on and off quickly. Discuss which mode of operation is most suitable and explain why.
Show hintHide hint
Consider the behavior of a switch.
Question 6.
In a specific application, losses during switching are significant if the BJT is not managed correctly. How can addressing the cut-off and saturation modes influence efficiency?
Show hintHide hint
Focus on the on/off cycle of the transistor.
