Potentiometer: Definition, Types, And Working Principle What is a Potentiometer? A potentiometer (also known as a pot or potmeter ) is defined as a 3 terminal variable resistor in which the resistance is manually varied to control the flow of electric current . A potentiometer acts as an adjustable voltage divider . How Does a Potentiometer Work? A potentiometer is a passive electronic component . Potentiometers work by varying the position of a sliding contact across a uniform resistance. In a potentiometer, the entire input voltage is applied across the whole length of the resistor , and the output voltage is the voltage drop between the fixed and sliding contact as shown below. A potentiometer has the two terminals of the input source fixed to the end of the resistor. To adjust the output voltage the sliding contact gets moved along the resistor on the output side. This is different to a rheostat , where ...
