WebA trimpot or trimmer potentiometer is a small potentiometer which is used for adjustment, tuning and calibration in circuits. When they are used as a variable resistance (wired as a rheostat) they are called preset resistors. Trimpots or presets are normally mounted on printed circuit boards and adjusted by using a screwdriver. WebA braking resistor is a resistor that generates a braking torque to slow or stop the speed of a mechanical system. These resistors are built to certain specifications, such as average braking power and resistance. Braking resistors with lower ohmic values will aid in controlling a motor’s speed and dissipating more heat.
