Show hintHide hint
Reflect on current response to input changes.
Question 5.
If an amplifier circuit has a feedback resistor of 100Ω and a gain of 10, what happens to the input resistance if you apply a feedback effect?
Show hintHide hint
Reflect on how resistors in parallel/series adjust overall resistance.
Question 6.
Explain how internal resistance affects the loading condition in feedback networks and what measures can be taken to mitigate this issue.
Show hintHide hint
Consider techniques common in circuit design.
