Challenge 1 Hard

Design a non-inverting amplifier circuit that can achieve a gain of 10 and use standard resistor values to represent Rf and Rg. Explain why your chosen values are appropriate.

💡 Hint: Adjust Rg and Rf appropriately while keeping gain in mind.

Challenge 2 Hard

What changes to the output voltage would occur if you increased Rf in an inverting amplifier while keeping Rin constant? Analyze the impact on gain.

💡 Hint: Refer to the formula for gain in inverting amplifiers.
