Potentiometer Circuit Diagram Symbol. They are mostly used to draw a circuit diagram and are standardized internationally by the ieee standard ieee std 315 and the british standard bs 3939. The variable resistor remains a two terminal device so the arrow is just laid diagonally across the middle.
Two terminals the blue and green are connected to a resistive element and the third terminal the black one is connected to an adjustable wiper. The variable resistor remains a two terminal device so the arrow is just laid diagonally across the middle. The circuit requires a 10k pot.
They are mostly used to draw a circuit diagram and are standardized internationally by the ieee standard ieee std 315 and the british standard bs 3939.
The two schematic symbols for a potentiometer are shown below. In electronic circuits there are many electronic symbols that are used to represent or identify a basic electronic or electrical device. A potentiometer is a resistor that has a mechanical shaft or screw that can be turned to change its resistance. They are mostly used to draw a circuit diagram and are standardized internationally by the ieee standard ieee std 315 and the british standard bs 3939.
