Practice Questions
Test your understanding with targeted questions related to the topic.
Question 1
Easy
What happens to input resistance when negative feedback is applied?
💡 Hint: Think about the relationship: R_in_f = R_in (1 + βA).
Question 2
Easy
Define load resistance in the context of feedback systems.
💡 Hint: It helps to think of loads in terms of their effect on voltage.
