Rotary potentiometers (RUS1R0E) are a class of variable resistors for use in electrical circuits. They are used to control the flow of current in a circuit, which in turn can be used to vary the voltage or power output of a device. Rotary potentiometers are typically built with three or four terminal pins, with one of the terminals typically connected to a voltage source. The resistance between two of the pins is varied by rotating a knob, which moves a wiper along an internal conductor. The resistance can be adjustable from zero to a maximum value, depending on the construction.

Rheostats are similar to rotary potentiometers, but have two terminals instead of three or four. In this type of device, the resistance between the two terminals can be continuously adjusted by rotating a knob, which moves a sliding contact along an internal conductor. Rheostats are most often used to adjust the light output from electronic lighting systems.

The working principle of both rotary potentiometers and rheostats is the same. A sliding contact is moved along an internal conductor, whose resistance is directly proportional to the length of the conductor. When the contact is moved along the conductor, the resistance can be adjusted from a low to high value, depending on the device\'s construction. The resistance adjustment is typically done by rotating a knob, which in turn moves the sliding contact along the internal conductor.

Rotary potentiometers and rheostats are used widely for a variety of applications, such as volume and tone control on electronic musical instruments, voltage and current regulation in power supply circuits, and position detection in automation systems. They are also used extensively in the audio and video industries for signal processing.

In addition, rotary potentiometers and rheostats are also used in the process control industry. By placing the devices in a feedback loop, the output of the process can be monitored and adjusted in order to maintain a given result. This is especially useful in chemical plants, where precise control is necessary for the production of high-quality products.

Rotary potentiometers and rheostats have a wide range of applications in many industries. They are easy to install and can be adjusted manually or electronically, depending on the type. As such, they offer increased flexibility in a variety of systems and can be used to regulate the current, voltage or power output of devices, as well as to monitor and adjust the output of process systems.
