Potentiometer Wiring Diagram Symbol

A little later we shall look at the many ways a standard pot may be wired as well as some further. 315 1975 graphics symbols for electrical and electronics diagrams paragraph 14 2 5 rotation description applied to a resistor states that the letters cw may be placed at one end of the potentiometer symbol to indicate the position of adjustable contact at the limit of clockwise travel viewed from the knob or actuator end. The above image shows a simple circuit to dim an led.

The potentiometers or the pots as it is commonly known in the electric circles is a three terminal variable resistor.

Potentiometer wiring diagram symbol. The standard schematic symbol for a pot is shown to the left. You will see that many people insist on using zig zag lines for resistors and pots i don t and haven t done do for at least 40 years so don t expect me to start again now. The diagram shows the parts present inside a potentiometer. If you need a simple resistor that you can change the resistance of you only need two pins.

Keep that in mind and have a look at the following three examples on how to wire a potentiometer. The middle pin and one of the side pins. We have a resistive track whose complete resistance will be equal to the rated resistance value of the pot. Mostly used to regulate the current flow by adding subtracting resistance from the circuit these resistors are available in many shapes and sizes.

Potentiometer working circuit diagram construction types resistor a small bundle of resistance is one of the most used basic components in an electric circuit. Potentiometer circuit diagram symbol and its working. As the symbol suggests a potentiometer is nothing but a resistor with one variable end.
