Subject: Potentiometer Wiper Voltage

Introduction: The circuit shown in Figure 1 produces an wiper voltage, vw, that represents the angle, -180 deg < theta < 180 deg, of a dial connected to the potentiometer.

Figure 1. Potentiometer used as a transducer.

Conclusion: The wiper voltage, vw, is related to the angle theta by the equation …
