In the circuit diagram shown below the terminals of the potentiometer are marked 1 2 and 3. The above image shows a simple circuit to dim an led.

Potentiometer wiring diagram. The middle pin and one of the side pins. The voltage supply is connected across terminals 1 and 3 positive lead to terminal one while negative lead to terminal three. They have a small shaft on top that functions like a knob. Keep that in mind and have a look at the following three examples on how to wire a potentiometer. Wiring illustration for using a potentiometer as a rheostat. As the symbol suggests a potentiometer is nothing but a resistor with one variable end.
If the maximum dissipation is 05w and the resistance is 10k then the maximum current that may flow through the entire resistance element is. Potentiometers or pots are a type of resistor used to control the output signal on an electronic device like a guitar amplifier or speaker. The standard schematic symbol for a pot is shown to the left. Assuming series or two terminal rheostat wiring. If you need a simple resistor that you can change the resistance of you only need two pins. How to wire a potentiometer.
Instructions for potentiometer wiring. Ohms law schematic diagram. For this experiment you will need a relatively low value potentiometer certainly not more than 5 kω. We have a resistive track whose complete resistance will be equal to the rated resistance value of the pot. Lessons in electric circuits volume 1 chapter 2. Lets look at the 05w pot and 10k is a good value to start with for explanation.
The diagram shows the parts present inside a potentiometer. The terminal 2 is connected to the wiper.
