POTENTIOMETERS A potentiometer is a resistor that has a mechanical shaft or screw that can be turned to change its resistance. A potentiometer is just a variable resistor: -> The longer the "trace" from W to either A or B, the higher the resistance. The two schematic symbols for a potentiometer are shown below: Rotary Potentiometers These are the most common type of potentiometers, where the wiper moves along a circular path. Linear Potentiometers In these types of Potentiometers the wiper moves along a linear path. Also known as slide pot, slider, or fader. Some Applications of Potentiometers Potentiometer as a Voltage Divider The potentiometer can be worked as a voltage divider to obtain a manual adjustable output voltage at the slider from a fixed input voltage applied across the two ends of the potentiometer. Now the load voltage across RL can be measured as VL= R2RL. VS/(R1RL...
