Question 1.
What is the purpose of a coupling capacitor in an amplifier?
Show hintHide hint
Think about how signals behave differently in AC and DC.
Question 2.
How does removing a coupling capacitor affect voltage gain?
Show hintHide hint
Remember the last class discussion on this topic.
3Question 3.
What role do coupling capacitors play in amplifier circuits?
- They block AC signals
- They combine resistances
- They allow AC signals to pass
Show hintHide hint
Think about how we utilize AC and DC in circuits.
4Question 4.
True or False: The absence of coupling capacitors decreases the input resistance of an amplifier.
- True
- False
Show hintHide hint
Recall our discussions on performance changes without components.
Question 5.
You have a common base amplifier with a specified coupling capacitor. If the input voltage is 1V and the gain calculated is 10.31, what is the expected output voltage if the capacitor is removed?
Show hintHide hint
Consider the effect of voltage gain reduction discussed in class.
Question 6.
Analyze a circuit where input resistance without the coupling capacitor is given as 580 kΩ. If you were to include a gain, how would that change based on the gain formula you learned?
Show hintHide hint
Revisit how changes in configuration alter resistance measurements in circuits.
