Rotary Potentiometers, Rheostats

Rotary Potentiometers, Rheostats (EVJ-C51F02B24) are among the most common devices used to control the electrical characteristics of other electrical/electronic components. These devices are usually used to measure or adjust a voltage, current or resistance of a given circuit. This article will discuss the application fields and working principle of the EVJ-C51F02B24.The EVJ-C51F02B24 is a rotary potentiometer. It is a three-terminal passive component that can be used to adjust an electrical voltage by changing the resistance of a single track. It typically consists of a resistive track, a moving contact (the wiper) that slides along the track, and terminals connected to either end of the track. When the wiper is set to one of the terminals, the resistance between both terminals is at its minimum. As the wiper moves away from the terminal, the resistance increases gradually in a logarithmic manner. The resistance value can be read via a measurement device. The principal application fields of the EVJ-C51F02B24 are in AC/DC motors, instrumentation amplifiers, and loudspeakers/headphones. In AC/DC motors, it is used for torque-speed regulation in which the calibrated wiper is used to adjust the speed of the motor. In instrumentation amplifiers, it acts as a variable gain amplifier to vary the DC gain of the amplifier. In loudspeakers/headphones, it allows for control of the volume, treble, and bass, as well as for equalization of frequencies. The working principle of the EVJ-C51F02B24 is based on the Ohm\'s Law equation for calculating electrical resistance. When an electrical current flows through a resistor, the electrical voltage is reduced by the resistance value. The EVJ-C51F02B24 has a resistive track with a wiper which slides along the track, thereby adjusting the overall resistance. When the wiper moves away from the terminal, the overall resistance increases because the overall resistance is the sum of the two resistances of the resistive track and the wiper\'s resistance. This increase in resistance causes an increase in voltage drop.Rotary Potentiometers, Rheostats can provide low cost and reliable control of electrical parameters, as well as provide full range of control with low temperature coefficients. The EVJ-C51F02B24 is a highly versatile rotary potentiometer that can be used in a variety of applications. The device is reliable, has low cost, and is easy to install and maintain. With the right selection of the track resistance range and the number of available tracks, this device offers great flexibility for different applications.
