Question 1.
What is a Common Base Amplifier?
Show hintHide hint
Think about the common terminal in an amplifier circuit.
Question 2.
What does a coupling capacitor do?
Show hintHide hint
Consider its role in signal isolation.
3Question 3.
What happens to the input resistance when the coupling capacitor is removed?
- Decreases
- Increases
- Remains the Same
Show hintHide hint
Consider how the circuit behaves without AC grounding.
4Question 4.

- True
- False
Show hintHide hint
Reflect on how earbuds work with and without DC sources.
Question 5.
If a Common Base Amplifier configuration shows an input resistance of 52 Ohms with a capacitor, what would be the expected input resistance if the capacitor is removed? Explain the underlying electrical principles.
Show hintHide hint
Focus on how signal dynamics change in your answer.
Question 6.
Analyze the trade-offs of removing the coupling capacitor in terms of stability and amplifier gain. Discuss how these factors impact real-world applications.
