Rotary Potentiometers and Rheostats

Rotary potentiometers and rheostats are two commonly used electronic components in the industry. Both of them are used for electrical signal control, such as voltage or current. They both play a crucial role in the management of electronic circuitry.

The main difference between a rotary potentiometer and a rheostat is found in the physical construction of the units. A rotary potentiometer consists of three terminals. It also has a rotating shaft with a contact on the end. By turning the shaft, a contact can be made which allows for an electrical connection from one terminal to either of the other two. This is done by a varying resistor value which changes depending on the angle of the shaft.

In contrast, a rheostat has two terminals along with a sliding contact that moves along a resistive path. Rheostats also vary resistance depending on how close it is moved along the resistive path. By there physical construction, rheostats are limited to providing a much lower resistance than potentiometers.

The JCL20 10k 0.5% rheostat is a linear type device that consists of both rotary and variable resistor elements. It has two terminals for connection. The resistance range is 5.5 - 10k ohms with an accuracy of 0.5%. It is a reversible device which means it can be used in one of two directions so that it can either create or limit an electrical signal.

The applications of this rheostat are very diverse and varied. It can be used as an adjustable resistance element in power conversion, current control in DC power supplies, regulation of voltages in industrial automation systems and as a dimmer switch for lighting.

In terms of working principle, the rheostat consists of two parts: a resistive element and a wiper. When connecting, the wiper to the terminals, a by-pass unit is online and ready to coil electricity. Therefore, the rheostat control the amount of electricity flow to the connected device by changing the wiper\'s position on the resistive element.

Overall, the JCL20 10k 0.5% rheostat is a useful device for managing the current in many electronic systems. It is flexible in its applications and can control a wide range of electrical signals, while still remaining accurate and efficient.
