The standard schematic symbol for a pot is shown to the left. Wiring illustration for using a potentiometer as a rheostat.
How To Use Potentiometer Arduino Tutorial 4 Steps With
Potentiometer wiring diagram. Keep that in mind and have a look at the following three examples on how to wire a potentiometer. 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. We have a resistive track whose complete resistance will be equal to the rated resistance value of the pot. 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.
Assuming series or two terminal rheostat wiring. If the maximum dissipation is 05w and the resistance is 10k then the maximum current that may flow through the entire resistance element is. For this experiment you will need a relatively low value potentiometer certainly not more than 5 kω. Ohms law schematic diagram. Instructions for potentiometer wiring. The above image shows a simple circuit to dim an led.
The terminal 2 is connected to the wiper. Lets look at the 05w pot and 10k is a good value to start with for explanation. Lessons in electric circuits volume 1 chapter 2. They have a small shaft on top that functions like a knob. In the circuit diagram shown below the terminals of the potentiometer are marked 1 2 and 3. How to wire a potentiometer.
The diagram shows the parts present inside a potentiometer. As the symbol suggests a potentiometer is nothing but a resistor with one variable end.
