Design an inverting amplifier with a gain of -50 using a 10 kΩ resistor for R₁. What size resistor do you need for R₂?
💡 Hint: Apply the gain equation we've discussed.
Create a differential amplifier circuit with R₁ = 5 kΩ, R₂ = 15 kΩ, R₃ = 5 kΩ, and R₄ = 15 kΩ. What will the voltage gain be?
💡 Hint: Focus on how the resistors set the gain for both inputs.
