At some point in an electronics project you might find yourself needing a variable resistor. The above image shows a simple circuit to dim an led.

How to wire a potentiometer.
Potentiometer wiring diagram. Ohm s law schematic diagram. Variable resistors are useful for the following. The potentiometer reduces costs by eliminating the need to design and build sealed protection against dust and moisture for the device in these applications.
The diagram shows the parts present inside a potentiometer. They have a small shaft on top that functions like a knob. Mostly used to regulate the current flow by adding subtracting resistance from the circuit these resistors are available in many shapes and sizes.
Adjustable gain of an amplifier adjustable cutoff frequency of an rc filter change the brightness of an led making measurements with a wheatstone bridge adjusting the sensitivity of sensors wired in series. The humble potentiometer or pot as it is more commonly known is a simple electro mechanical transducer. Instructions for potentiometer wiring.
It converts rotary or linear motion from the operator into a change of resistance and this change is or can be used to control anything from the volume of a hi fi system to the direction of a huge container ship. Potentiometers or pots are a type of resistor used to control the output signal on an electronic device like a guitar amplifier or speaker. If you need a simple resistor that you can change the resistance of you only need two pins.
Potentiometer working circuit diagram construction types resistor a small bundle of resistance is one of the most used basic components in an electric circuit. Keep that in mind and have a look at the following three examples on how to wire a potentiometer. Bushing l and n feature life of 2 million cycles while bushing t q o and p offer 1 million cycles.
Here s how to make one using a potentiometer. The p13l is available in six bushing options and body sizes of 12 6 mm 14 mm and 16 mm. The middle pin and one of the side pins.
As the symbol suggests a potentiometer is nothing but a resistor with one variable end. Wiring illustration for using a potentiometer as a rheostat. For this experiment you will need a relatively low value potentiometer certainly not more than 5 kω.
Lessons in electric circuits volume 1 chapter 2. We have a resistive track whose complete resistance will be equal to the rated resistance value of the pot.
