Question 1
What is the formula for the gain of a non-inverting amplifier?
- A_v = \\frac{R_f}{R_{in}}
- A_v = 1 + \\frac{R_f}{R_{in}}
- A_v = \\frac{R_{in}}{R_f}
π‘ Hint: Remember the significant contribution of both resistors in the formula.
Question 2
True or False: Non-inverting amplifiers invert the phase of their input signal.
- True
- False
π‘ Hint: Consider how the amplifier's output relates to its input.

Question 1
Given a non-inverting amplifier with R_f = 20 kΞ© and R_{in} = 5 kΞ©, calculate the gain. Explain your working.
π‘ Hint: Substitute the resistor values into the gain formula.
Question 2
In a practical circuit, you notice a 1:1 gain in a non-inverting amplifier setup. Why might this be happening based on the resistor values?
π‘ Hint: Consider what happens to the gain when resistors are set to extreme values.
