Question 1.
What are the input characteristics of a common emitter configuration?
Show hintHide hint
Think about how current reacts to voltage.
Question 2.
Explain the significance of the output characteristics in a common emitter configuration.
Show hintHide hint
Consider what happens at saturation.
3Question 3.
What does the input characteristics curve display?
- I_B vs. V_BE
- I_C vs. V_CE
- I_C vs. I_B
Show hintHide hint
Remember the first variable listed in the curve.
4Question 4.
True or False: In a common emitter configuration, increasing V_CE leads to a linear increase in I_C until saturation.
- True
- False
Show hintHide hint
What happens to the current as you keep increasing voltage?
Question 5.
If a common emitter BJT has a current gain (β) of 100 and the base current (I_B) is 20 µA, what will be the collector current (I_C)?
Show hintHide hint
Apply the formula for current gain.
Question 6.
Describe the output characteristics of a common emitter configuration when transitioning from cutoff to saturation. What happens to I_C?
Show hintHide hint
Think about current behavior in both states.
