Potentiometer RM065 (204)
Potentiometer RM065 (204) Also called a trimmer, variable resistor or a pot for short.
Blue and white in color.
Can be precisely set to any value between 0 and 10K or used to get variable results as for example a volume control or speed changer.
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.
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.
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.
There are a number of terms in the electronics industry used to describe certain types of potentiometers:
- slide pot or slider pot: a potentiometer that is adjusted by sliding the wiper left or right (or up and down, depending on the installation), usually with a finger or thumb
- thumb pot or thumbwheel pot: a small rotating potentiometer meant to be adjusted infrequently by means of a small thumbwheel
- trimpot or trimmer pot: a trimmer potentiometer typically meant to be adjusted once or infrequently for “fine-tuning” an electrical signal
