Potentiometer Circuit Diagram And Working. The diagram shows the parts present inside a potentiometer. As the symbol suggests a potentiometer is nothing but a resistor with one variable end.
These potentiometers are available in different shapes and include three leads. The pin diagram of the trimpot potentiometer is shown below. 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.
If only two terminals are used one end and the wiper it acts as a variable resistor or rheostat.
A potentiometer is a passive electronic component. These potentiometers are available in different shapes and include three leads. So a 200k pot can provide a maximum of 200 000 ohms of resistance. The only potentiometer we have on hand is a 10 kω unit.
