Randall P Robert 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 Circuit Diagrams: **Refer to this diagram for the table below.
