Rotary Potentiometers, also known as rotary variable resistors, are resistors used for measuring electrical current. They are generally located in electronics and other electronic equipments, as they are a practical and simple control device. Rheostats, on the other hand, are resistors that are designed to regulate current flow. They are also used in electronics and are mainly found in audio amplifiers.

PDB182-K418F-103B is a type of rotary potentiometer. It is a 3-terminal rotate-type linear multi-turn potentiometer composed of a ceramic wiper, a shaft, terminals, and a case. It is designed and specified for use in areas where compact size and wide range of angular adjustment is required such as instrumentation and sound level measurement, panel meter, equalizer, and level control.

The PDB182-K418F-103B features an internal contact assembly built with a ceramic wiper connected to a conductive shaft. The ceramic wiper ensures long life and durability as it is harder and smoother than metal wipers. The conductive shaft is made of steel or polypropylene and is corrosion resistant. The entire assembly is encapsulated in an epoxy potting compound within a robust Metal Can Package.

The working principle of a PDB182-K418F-103B is simple and straightforward. When the unit is rotated, the wiper arm slides along the resistance element. As the wiper arm moves, it acts as a bridge to the resistance element, and the output voltage is generated. This output voltage can be used to measure the angle of rotation, as the resistance value is directly related to the angle of rotation. This output voltage can then be used as an input for other devices, such as switches, timers, and displays.

Rheostats are resistors that change the current flow in an electric circuit by providing varying resistance values with a single adjustable parameter. They can be used as the primary control element in a circuit, with the voltage or current being varied by the rheostat\'s setting. Rheostats are used in a variety of applications, such as lighting controls, frequency control, temperature controller, voltage regulation, and current regulation.

Many electronic devices rely on rheostats to adjust or monitor current. Digital and analog meters, motor speed control, and many other circuits rely on rheostats to adjust or measure current flow. In these circuits, the rheostat is connected in series with the load, and the amount of current will be varied by turning the knob of the rheostat. The output voltage is then adjusted accordingly.

The working principle of a rheostat is simple and straightforward. As the knob is turned, the resistance value of the rheostat changes accordingly, thus allowing the amount of current to be adjusted. The output voltage is adjusted depending on the set resistance value. Higher resistance values reduce the amount of current allowed to flow, while lower resistance values increase the current. This enables the rheostat to be used as a control device to regulate current in an electric circuit.

The PDB182-K418F-103B and Rheostats are two essential components found in a variety of electronic devices. The PDB182-K418F-103B is a 3-terminal rotary potentiometer used for measuring electrical current while the Rheostats are resistors designed to regulate current flow. Both components have distinct working principles, but both can be used to control current in circuits.
