Rheostats - The Device Specifically Made to Control Electrical Resistance of a Circuit


What is Rheostat and why is it used for?

A rheostat is a device that is utilized in aviation, aerospace, industrial, and commercial industries. This device is associated with the electrical circuit part family. A rheostat is an adjustable resistor that is used to control the electrical resistance of a circuit without interrupting the flow of electrical current to that circuit. A rheostat regulates electric current by increasing or decreasing the resistance of the circuit. It is merely a coil of resistance wire with a slider on it so that the resistance can be varied. Rheostats operate by having current flow into the resistance coil and then through the slider. When the control knob is turned, the slider moves along the coil. Once this occurs, the amount of resistance can be changed by varying the length of the current’s path through the resistance coil. Rheostats are mainly used for appliances and other items that need high voltage and electrical currents that can be interrupted. Some common uses of the rheostat are:

  • Dim lights
  • Control speed of an electric motor
  • Battery charging
  • Control volume of a radio

Rheostats and their Assistance with Lighting:

When it comes to being used for lighting, rheostats assist with setting levels for comfort or mood. Rheostats also allow consumers to change light levels without needing to change lights. In the aerospace and aviation industries, rheostats are used for panel light dimming.

Select the Best Manufacturer from the List of Many:

Many companies manufacture rheostats due to the fact that these devices are utilized for many applications. For example, Cessna, which is considered the leader within the aviation industry with the world’s bestselling aircrafts and the largest fleet of business jet aircrafts in the world, manufactures rheostats on a regular basis. Many of their aircrafts use rheostats for their panel lighting.
