EE 2231 Suhas Patel February 5, 2004 Randall Robert Objective: To study voltage division in circuits with potentiometers. Procedures: 1. Connect a potentiometer as in figure 1a. Record the output voltage as a function of the potentiometer position. 2. Add a 10 k resistor to the POT tap and repeat step 1. The result will not be identical to procedure 1. At the middle setting the output voltage will be 4V rather than 5V. 3. Figure 2a is obvious. Figure 2b is a rough approximation to a transistor with finite output resistance. Think of the 3.3 k resistor as a collector resistor (it will make sense later in 2230). Record the output voltage as a function of POT position. If the transistor were a perfect
