Music for this Problem

Each of the graphs below shows the output voltage V_o of a certain circuit as a 5K\Omega potentiometer is turned linearly from \alpha = 0 to \alpha = 1.

Response A:
Response B:
Response C:
Response D:
Response E:
Response F:
Response G:

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
