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

Step 1: Knowing the potentiometer

Turn the potentiometer and you will see the maximum resistance value of the potentiometer engraved over it. Here 1Mega ohm is the maximum value of resistance this potentiometer has.
<p>794? Isn't it supposed to measure 1M or within 10 percent of it?</p>
