Analog design engineers frequently setresistances and voltages to make analog circuits meetspecifications. By using potentiometers to control the parametersof circuits, engineers can calibrate or vary ...

To get around the built-in short-circuit protection he needed a potentiometer to limit the current while allowing for adjustments. His first circuit used a resistor salvaged from an AT supply and ...

Potentiometers, rheostats, and trimmers are adjustable resistors used to measure or divide voltages in order to protect or control circuits. The terminology surrounding potentiometers and related ...

Digital potentiometers are three-terminal resistors with an adjustable center connection. To set the output resistance, a digital signal is sent through an electrical interface. There are two main ...

Motorized linear potentiometers are a rare, exotic, and just plain neat input device most commonly found on gigantic audio mixing boards and other equipment that costs as much as a car.
