Question 1
What is the voltage gain equation for a common source amplifier?
- A = V_out / V_in
- A = R_D * g_m
- A = -R_D * g_m
💡 Hint: Consider how output voltage behaves with respect to input.
Question 2
True or False: The output resistance increases with increasing load resistance.
- True
- False
💡 Hint: Think about how loading changes the output voltage instead.

Question 1
Calculate the voltage gain for a common source amplifier if R_D = 10 kΩ and g_m = 1 mA/V. What implications does the gain level present?
💡 Hint: Use A = -R_D * g_m to find the gain.
Question 2
Discuss how increased output resistance affects amplifier behavior when connected to different loads.
💡 Hint: Focus on the implications of Ohm's Law in signal transfer.
