What is Potentiometer And How it Works Spectra Symbol
A potentiometer is an electrical component with a variable resistor whose value is changed
manually.
This device adjusts the voltage or current flow in a circuit.
One device frequently used
as a voltagedividing component is the potentiometer, which is a resistor with a movable element
positioned by a manual knob or lever which are used to control such parameters as volume,
treble, bass, brightness and contrast.
Unlike with a normal resistor, the resistance of a
potentiometer can be changed, usually either by turning a knob or adjusting a slider.
Potentiometers are used to control a wide variety of different circuits including thermostats,
dimmer switches and even joysticks.
Potentiometers work by having a resistive element inside.
Both end terminals are attached to it,
and do not move.
The symbol for a potentiometer is the same one as a resistor, save for an
arrow in the middle.
