Many of us have used potentiometer
in our day to day life, for example varying the volume of your music system by rotating the knob, controlling the brightness of your television by pressing a button on the remote. Behind all these mechanism Potentiometer is there which is controlling the sound level or the brightness level of your gadget.
Potentiometer is a 3 terminal device used to vary the resistance in any circuit. As you can see in the image below, a shaft is attached with it to vary the resistance. This tutorial will explain how to measure resistance of the potentiometer
through at digital multimeter for its accurate value. If you want to know more about this electronic component, check this pin diagram
, and an insight on working of potentiometer Apparatus required:
1. Digital Multimeter
2. Linear potentiometer
