Web31 aug. 2024 · A potentiometer is normally called as pot and it has three terminals. The pot ends are connected across the battery source. To know how potentiometer is used as a rheostat, three pinouts are used. Out of three pins, only two pins are used. One terminal is the outside pin with knob or screw and another terminal is the middle one. WebIf only two terminals are used, one end and the wiper, it acts as a variable resistor or rheostat . The measuring instrument called a potentiometer is essentially a voltage divider used for measuring electric potential …
Web28 nov. 2024 · A 3 terminal pot used with 3 terminals, is basically just a voltage divider. As you move the wiper, you increase one resistor in the voltage divider, while decreasing the resistance in the other. ... Connecting a wiper to one leg of the pot, is a rheostat. A … WebTechnically, a variable resistor is known as a rheostat. Step 1: In its simplest configuration, a potentiometer may be used as a rheostat by simply using the wiper terminal and one of the other terminals, as illustrated in Figure 2. Figure 2. The changing resistance of a potentiometer as a function of the terminals.
