Question 1.
Define voltage gain in simple terms.
Show hintHide hint
Think of it as how much the amplifier increases the signal.
Question 2.
What happens to output resistance in an ideal feedback network?
Show hintHide hint
Recall the relationship between feedback and output resistance.
3Question 3.
What is the relationship between the input and output resistance in a feedback system?
- Input resistance increases
- Output resistance increases
- Both resistances remain the same
Show hintHide hint
Think of the impact of feedback on circuit performance.
4Question 4.
True or False: Introducing feedback to an amplifier always increases gain.
- True
- False
Show hintHide hint
Consider the effects of feedback discussed earlier.
Question 5.

Show hintHide hint
Use the definitions of gain and feedback factor to construct your formula.
Question 6.
Discuss the trade-offs between high gain and system stability in feedback systems.
Show hintHide hint
Reflect on practical examples in amplifier design where balance is key.
