Slideshare uses cookies to improve functionality and performance, and to provide you with relevant advertising. Potentiometer (pot) The potentiometers or the “pots”, as it is commonly known in the electric circles, is a three terminal variable resistor. To understand it more simply, if you are applying 5 volt for driving a motor then motor will moving with some speed, now if we reduces applied voltage by 2 means we apply 3 volt to motor then motor speed also decreases. The working phenomenon of DC potentiometer and AC potentiometer is same. See our Privacy Policy and User Agreement for details.
