Question 1
What is the formula to calculate the input power (P_in) for an amplifier?
- P_in = V_CC * I_CQ
- P_in = V_out * R_L
- P_in = I_CQ / V_CC
💡 Hint: Recall the formula discussed in class about power input.
Question 2
True or False: Higher efficiency indicates that an amplifier can convert more DC power into AC power effectively.
- True
- False
💡 Hint: Think about how effectiveness is usually measured in electronics.

Challenge Problems
Push your limits with challenges.
Question 1
An amplifier has V_CC = 15V and draws current I_CQ = 0.03A. Calculate the total input power and inferred output power if the load resistance is 6Ω and the peak-to-peak voltage is 6V.
💡 Hint: First compute the input power before estimating the output.
Question 2
Describe the consequences of feedback on amplifier distortion and stability, providing a scenario where negative feedback might lead to increased stability.
💡 Hint: Consider how adjusting feedback affects circuit performance in real applications.
