Know That Potentiometer | How to Test and Measure Resistance

In this video, we explore one of the most commonly used electronic components in circuit design and prototyping — the Potentiometer, also known as a Pot, Trimmer, or Variable Resistor. You will learn: • What a potentiometer is and how it works • Identification of pins and pin configuration • How to read the value printed on the component body • Understanding the 10k potentiometer marking • Difference between fixed and variable resistance • How to place the potentiometer correctly on a breadboard • How to test a potentiometer using a Digital Multimeter (DMM) • How resistance changes between different pin combinations • Clockwise and anticlockwise resistance variation demonstration • Practical use of potentiometers in electronic circuits and PCB designs In this practical electronics tutorial, we demonstrate step-by-step measurement of resistance between: Pin 1 and Pin 3 (fixed total resistance) Pin 1 and Pin 2 (variable resistance) Pin 2 and Pin 3 (variable resistance) You will also see how turning the potentiometer knob changes resistance values in real time and how this component is used in actual electronic hardware and prototyping applications.
