Potentiometer Schematic. The measuring instrument called a potentiometer is essentially a voltage divider used for measuring electric potential voltage. How does a potentiometer work.
The ground is all the way off terminal 2 is the switch itself and terminal 3 is the switch turned all the way up. A potentiometer is a resistor that has a mechanical shaft or screw that can be turned to change its resistance. The component is an implementation of the.
Potentiometers are also called pots for short.
A potentiometer is almost always used to throttle an input signal so that it can be adjusted. A potentiometer acts as an adjustable voltage divider. If it helps think of a potentiometer as a dimmer switch. The greater the resistor value the smaller the current will flow.
