Potentiometer wikipedia
A potentiometer 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. It works by sliding a conductor in a graphite disk that has a stable resistance depending on the … See more Some terms in the electronics industry used to describe certain types of potentiometers are: • Slide pot or slider pot: a potentiometer that is adjusted by sliding the wiper left or right (or up and … See more The most common way to vary the resistance in a circuit continuously is to use a rheostat. It is basically used to adjust magnitude of current in a circuit by changing length. The word rheostat was coined about 1845 by Sir Charles Wheatstone, … See more A membrane potentiometer uses a conductive membrane that is deformed by a sliding element to contact a resistor voltage divider. Linearity can range from 0.50% to 5% … See more • Potentiometric sensor • Trimmer See more Potentiometers consist of a resistive element, a sliding contact (wiper) that moves along the element, making good electrical contact … See more A digital potentiometer (often called digipot) is an electronic component that mimics the functions of analog potentiometers. Through digital input signals, the resistance between two terminals can be adjusted, just as in an analog … See more Potentiometers are rarely used to directly control significant amounts of power (more than a watt or so). Instead they are used to adjust the … See more WebA potentiometer is a type of variable resistor. These passive components are designed to control electrical resistance, measured in Ohms (Ω). Multiple different variations are …

Linear potentiometers produce a resistance output that varies according to the displacement or position of a slider or wiper. They are variable resistors with three leads. Two leads connect to the ends of the resistor, so the resistance between them is fixed. The third lead connects to a slider that travels ... imed laboratoriesWeb22 May 2024 · A potentiometer is a resistor with three leads. Along with the typical end leads, there is a third lead referred to as the wiper or tap. This third lead is connected to a small metallic arm that makes contact with the resistive material and which can be moved along the length of the material.

If a sensitive indicating instrument is used, very little current is drawn from the source of the unknown voltage. Since the reference voltage can be produced from an accurately calibrated voltage divider, a potentiometer can provide high precision in measurement.
