In the circuit pictured below, R1=100Ohm and R2 is the potentiometer shown on the left.   If we want to use the circuit to power a 6V device connected to Vout with a 9V battery connected to Vin, what resistance (in Ohms) should the potentiometer be set to?

Given that R1=3kOHM, R4=6kOHM, R2=5kOHM, R3= 10kOHM, Rf1=20kOHM, Rf2=20kOHM, what would be the value of Vout if Vin1=Vin2=Vin3=1 V?

A first-order passive high pass filter with load resistor circuit is shown as below:   If R= 10kΩ, C=0.01uF, What is the cutoff frequency for this filter in Hz?

The circuit below is a variable gain amplifier.
