1) Configuration 1
In this configuration, we will consider a circuit with a single 5k potentiometer (R_p = 5k\Omega), and a load resistor with resistance R connected to ground:
Which response results from this configuration with R=100k\Omega?
Which response results from this configuration with R=1k\Omega?
Which response results from this configuration with R=1\Omega?
2) Configuration 2
In this configuration, we will consider a circuit with a single 5k potentiometer (R_p = 5k\Omega), and a load resistor with resistance R connected to 10V:
Which response results from this configuration with R=100k\Omega?
Which response results from this configuration with R=1k\Omega?
Which response results from this configuration with R=1\Omega?
3) Configuration 3
In this configuration, we will consider a circuit with a single 5k potentiometer (R_p = 5k\Omega), and load resistors with resistance R connected both to ground and to 10V:
Which response results from this configuration with R=100k\Omega?
Which response results from this configuration with R=1k\Omega?
Which response results from this configuration with R=1\Omega?
