Top 12 Rheostats

Sir Charles Wheatstone invented the rheostat. He coined the term 'rheostat' in 1845, where rheos means' stream' and stats means 'to set, cause to stand.' Hence, rheostat means a setter or regulating device. The rheostat is a two-terminal variable resistor. It has become popular since being called an adjustable resistor.

Rheostats Buying Guide

A rheostat has many different uses. However, in general terms but rheostat is a device that alters current. It is also a device used in applications that can assist in varying the electric current resistance. This device can dim lights, change generator characteristics, and start or control the speed of motors. 

Importance of the resistance element 

A rheostat has many resistance elements for different purposes. It can use a metal wire, ribbon, carbon, or a conducting liquid based on its application. For average currents, the metallic type is most commonly used as a resistance element. However, if it is a minimal current, then the conducting type is used; if a substantial current is detected, an electrolytic type of resistance element is used where a conducting fluid is put into place. 

Selection based on application 

One must buy a rheostat based on its application. If many high currents or high voltage are involved, one should consider a large rheostat to handle a more massive current. Those devices that require a lesser amount of current require a different kind of rheostat to be used along with it to ensure that current overload does not happen, resulting in overheating and the product does not damage quickly.

Various applications around

A rheostat performs various functions depending on the need of the user. People often use the rheostat in tube lights and other light sources to adjust its light intensity. They are also used to control and adjust the speed of an electric motor. However, the rheostat's most critical application may be its heaters, ovens, and many other electronic appliances. Its presence is essential since it ensures that overheating does not occur. Its varied applications have made it very popular in the electronic industry.
