Lab #2 The Study of Voltage Division
Objective:
To study voltage division in circuits with potentiometers.
Procedures:
1.
Set the voltage to ~10.0 V.
2.
Connect a potentiometer as shown in figure 1a.
Record the output
voltage at one hour intervals with reference to the position of
the dial on
the potentiometer.
3.
Add a 10k resistor to the potentiometer tap and repeat the voltage
.
recording.
4.
assemble the components to resemble that of figure 2b and record the
voltages.
5.
Assemble figure 3b and record voltages as in the previous steps
