Practice Questions
Test your understanding with targeted questions related to the topic.
Question 1
Easy
What is the output voltage when the input is 100 mV and the gain is 10?
💡 Hint: Apply the formula: Output Voltage = Gain x Input Voltage.
Question 2
Easy
Define the term 'voltage gain'.
💡 Hint: Think about how much the input signal is amplified.

Question 1
What is the effect of negative feedback on the voltage gain?
- It increases voltage gain
- It has no effect
- It decreases voltage gain
💡 Hint: Think about how feedback helps control outputs.
Question 2

Challenge Problems
Push your limits with challenges.
Question 1
In a feedback system with A = 250 and β = 0.05, calculate the new voltage gain if the input signal is 200 mV and derive the final output voltage.
💡 Hint: Make sure to start from calculating the voltage gain first!
Question 2
Discuss how altering β from 0.05 to 0.1 impacts the new output voltage and input/output resistances. Assume A remains constant.
💡 Hint: Reference how we calculated resistances related to feedback factors.
