As the symbol suggests a potentiometer is nothing but a resistor with one variable end. The middle pin and one of the side pins.
How To Connect A Potentiometer In A Circuit
Potentiometer wiring diagram. Lessons in electric circuits volume 1 chapter 2. How to wire a potentiometer. We have a resistive track whose complete resistance will be equal to the rated resistance value of the pot. They have a small shaft on top that functions like a knob. Instructions for potentiometer 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.
The standard schematic symbol for a pot is shown to the left. Lets look at the 05w pot and 10k is a good value to start with for explanation. In the circuit diagram shown below the terminals of the potentiometer are marked 1 2 and 3. If you need a simple resistor that you can change the resistance of you only need two pins. The above image shows a simple circuit to dim an led. Assuming series or two terminal rheostat wiring.
The terminal 2 is connected to the wiper. The diagram shows the parts present inside a potentiometer. Wiring illustration for using a potentiometer as a rheostat. The voltage supply is connected across terminals 1 and 3 positive lead to terminal one while negative lead to terminal three. For this experiment you will need a relatively low value potentiometer certainly not more than 5 kω. 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. Ohms law schematic diagram.
