An operational amplifier with a feedback factor of 0.02 has an open-loop gain (A) of 100. Calculate the closed-loop gain.
💡 Hint: Plug in the values to the closed-loop gain formula.
In a Voltage Series Feedback configuration, the input impedance is 15kΩ, with a closed-loop gain of 5. Determine the new input impedance if the feedback factor is 0.05.
💡 Hint: Multiply the open-loop impedance by the factor from feedback and gain.
