Question

A rotary potentiometer is used in a music system that can rotate to a maximum angle of 263.8° and has a total resistance of 7.19kΩ. After the application of displacement, the angle of the potentiometer changes from 19.8° to 133.4°. It is connected to a 9.37V DC power supply. Calculate the following: i) Resistance R12 ii) Output voltage iii) Sensitivity in Ω/V iv) Input voltage of the sensor when the change in resistance is 4.82kΩ.

Step 1

8° and 133.4°). R12 = 7.19kΩ * ((133.4° - 19.8°)/360°) = 2.98kΩ ii) Output voltage can be calculated using the formula: Vout = Vin * (R12/Rtotal) where Vin is the input voltage of the potentiometer (in this case, 9.37V). Vout = 9.37V * (2.98kΩ/7.19kΩ) = Show more…
