Replace Potentiometer With Resistor Volt Ampere Meter Volt Install the new potentiometer and fix it.solder a lead on the original potentiometer pin slice, solder it on the corresponding pin slice of the new potentiom. Now that you know vin, z1, and your desired range of vout, you need to solve for z2. the max vout that you want is 5v, so lets plug that all into the voltage divider equation. 5v = (z2 (2kohm z2))*10v => z2 = 2kohm meaning that your pots max resistance should be 2 kohm. correlating voltage to degrees on the pot.
Wiring A Potentiometer As A Variable Resistor Figure 1. using a potentiometric voltmeter to measure an unknown voltage. the reference voltage is adjusted using a calibrated potentiometer. as this experiment will demonstrate, the simple act of measuring a circuit voltage can change the voltage we wish to measure. the potentiometric voltmeter can eliminate the effect on the device under test. You can move the point where the wiper connects to the carbon strip by turning the shaft of the potentiometer. when you move the wiper to the left side, the resistance between the middle pin and the left pin decreases. and the resistance between the middle pin and the right pin increases. move the wiper to the right, and the opposite happens. A potentiometer is a three terminal device acting as a voltage divider (figure 2, left), while the rheostat is a two terminal adjustable resistance which controls current flow. the potentiometer is often wired to create a rheostat which can be done in one of three similar ways, by leaving an end terminal unconnected or connected directly to the. Testing find the best resistance for your circuit before soldering a non variable resistor in permanently. normally, potentiometers are wired as variable voltage dividers: connect v to one side, connect the other side to ground, and the middle pin will output a voltage between 0 and v (fig 2). however, by only connecting two pins (one.

Instrumentation and electrical design. potentiometer equation and calculator. a potentiometer or a resistor a pot, is a three terminal resistor with a sliding or rotating contact that forms an adjustable voltage divider. if only two terminals are used, one end and the wiper, it acts as a variable resistor or rheostat. potentiometer.
