Potentiometer Wiring Diagram Symbol. A potentiometer or pot for short is an electronic component that functions as a variable resistor. Resistance small bundle of resistance is one of the most commonly used primary components in the electric circuit.
The symbols represent electrical and electronic components. Injunction of two wires is generally indicated by black dot in the intersection of two lines. How does it work.
Let us assume a 10k potentiometer here if we measure the resistance between terminal 1 and terminal 3 we will get a value of 10k because both the terminals are fixed ends of the potentiometer.
The main component within the pot is a resistor illustrated between terminals a and b above. Fwiw ieee std. A potentiometer is just a resistor current can flow through it in any direction including fromto both ends tofrom the wiper. Out of its three terminals two of them are fixed and one is a varying linear rotary terminal.
