Potentiometer parts and functions
WebPotentiometers find their most sophisticated application as voltage dividers, where shaft position determines a specific voltage division ratio . However, there are applications where we don’t necessarily need a variable voltage divider but merely a variable resistor: a two-terminal device. Technically, a variable resistor is known as a rheostat.

In addition to single potentiometers, such as the AD5245, AD5246, and AD5247, digital potentiometers are available as duals, triples, quads, and hex versions. Multiple devices per Web22 Sep 2024 · Any potentiometer is constructed of the following parts: The terminals: As already discussed, the potentiometer has three terminals, two fixed and one variable. …
WebA potentiometer made from homogenous resistance wire of length l and resistance R = al is used to changed voltage at an appliance of resistance R . Find the voltage across and current through a resistor R as a function of the distance x of the sliding contact from the end of the potentiometer. Hint Analysis Illustrating picture Solution Answer Web29 Sep 2024 · Potentiometers also known as POT, are nothing but variable resistors. They can provide a variable resistance by simply varying the knob on top of its head. It can be classified based on two main parameters. One is their Resistance (R-ohms) itself and the other is its Power (P-Watts)rating.
