29. 29Why your source follower stops following✓ published
30. 30Why your voltage follower is fast up and slow down✓ published
31. 31You found the voltage. Now you can't trust the resistance.✓ published
32. 32Close the switch. Half the energy is gone. Where did it go?✓ published
33. 33Zero resistance. Half the energy still vanishes.
34. 34This amplifier wants ZERO input resistance. Why?
35. 35How do you cancel an error nobody measured?
36. 36This resistor is making noise. Nothing is connected.

38. 38Copy your amplifier once. Distortion drops from 13% to 5%. Why?
39. 39One resistor took distortion from 5% to 0.2%. What did it cost?
