Practical wok:
I will use new simulation program called Proteus.
Do not worry, I do not want you to learn the program only analysis the results.

Part#1:
1) Connect the circuit as shown:

Part#1:
2) Draw the direct voltage (appeared on ch1) using oscilloscope.
3) Vary the potentiometer and notice the movement of the dot on Ch2 while varying, then draw the waveform.

Part#1:
In the report calculate the value of the previous
voltage, if you know the configuration of oscilloscope
as shown:

Part#1:
Remember:
The value of voltage = # of square x scale of ch
So the solution of the previous voltage is
V= - 0.9 x 5 = - 4.5 volte
