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 …
Finding: ...
1 comment:
Potentiometers can be obtained with either linear or logarithmic relations between the slider position and the resistance (potentiometer laws or "tapers").
