• Rotary Potentiometers

  A Rotary Potentiometer, often simply called a pot, is a type of electrical component known as a variable resistor. These particular components can be adjusted or rotated clockwise or counter-clockwise to vary the resistance, or the amount of current passing through it.RJS150E is an example of a rotary potentiometer, commonly used in a variety of electronic applications such as volume control, stereo tuning, and other tasks that require an adjustable resistance. It is a 15mm size three terminals rotary potentiometer, featuring a flat outer surface, a solid shaft, and three terminals.

  Application Field and Working Principle

  The RJS150E can be used in various types of electronic projects and circuits, such as amplifiers, radiotelephones, stereos, and other applications that require a variable resistor. It works by changing the resistance between the two outer terminals, based on the amount of rotation given to the shaft.

  The RJS150E operates with an internal resistive track connected to the shaft. As the shaft is rotated, the resistance value changes between the inner and outer terminals, with the resistance reaching its lowest value when the shaft is turned in a counter-clockwise direction. In this way, the RJS150E acts as a variable resistor, allowing you to adjust the amount of current passing through it.

  The resistance value of the RJS150E ranges from zero ohms to at least one million ohms, depending on the model. It also comes with a variety of knobs, allowing users to easily control and adjust the resistance as needed for their particular application.

• Rheostats

  Rheostats are another type of variable resistor, used in a variety of electronic applications to control the amount of current flowing. Like Rotary Potentiometers, Rheostats are adjustable, allowing for fine tuning of the current flow.

  Application Field and Working Principle

  Rheostats are commonly used in applications that require precise current control, such as lighting controls, audio amplifiers, electric motors, and other electronic equipment. They are also used in power supplies and other circuits that need to regulate the amount of current passing through them.

  The operation of Rheostats is based on the principle of changing the resistance between two electrical contacts. As with a Rotary Potentiometer, the resistance between the contacts will change depending on the amount of rotation given to the shaft. This allows for precise control over the amount of current passing through the device.

  The resistance of a Rheostat can range from a few ohms up to hundreds or even thousands of ohms, depending on the model. It also comes with a variety of knobs for easy adjustment.
