What Is A Slide Potentiometer?

Slide potentiometers (Pots) employ a resistive element and a sliding contact to form an adjustable voltage divider. If only two terminals are used, one end of the element and the adjustable contact, it acts as a variable resistor or rheostat.

How Does A Slide Potentiometer Work?

Linear or slide 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 along the resistor varying the resistance between it and the other two connections. The resistance element is excited by either DC or AC voltage.

Note that "Linear" can also refer to the taper (law) defining how the output voltage varies with the motion of the slider. A linear taper means that resistance increases in direct proportion to the distance travelled along the resistive element. This contrasts with a change in resistance via a logarithmic scale (a log or audio taper).

Resistive element types can be carbon (inexpensive), cermet (relatively limited life), conductive plastic (long life), or wire wound (current drawn during use).

Features of Slide Potentiometers

  • Q What is Potentiometer?


    A potentiometer is a three-terminal resistor with a sliding or rotating contact that forms an adjustable voltage divider.[1] If 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 (voltage); the component is an implementation of the same principle, hence its name.

    Potentiometers are commonly used to control electrical devices such as volume controls on audio equipment. It is also used in speed control of fans. Potentiometers operated by a mechanism can be used as position transducers, for example, in a joystick. Potentiometers are rarely used to directly control significant power (more than a watt), since the power dissipated in the potentiometer would be comparable to the power in the controlled load.
