AR300KL.25 Application Field and Working PrincipleRotary Potentiometers, Rheostats are electric devices used to measure the quantity of electrical energy in a circuit. They measure the amount of potential difference (PD) between two points in a electrical circuit, such as between the terminals of a battery or between any two points of an electrical circuit.Rotary potentiometers are especially popular because of their simplicity and affordability, which make them a great choice for a wide range of applications. They are available in most electronics retailers and online stores, and come in a variety of shapes, sizes and specifications.The AR300KL.25 is one such model of rotary potentiometer, and is made up of a rotating spindle, which is connected to two terminals. When the spindle is rotated, the resistance between the two terminals of the potentiometer changes. This change in resistance is then used to measure the current in a circuit.The main advantage of using an AR300KL.25 rotary potentiometer is that it can measure a wide range of current. This is especially important in applications such as motor control or power electronics, where the current might range from a few milliamps to hundreds of amps. This means that it is possible to measure current in a range of applications, from domestic electrical circuits to large industrial processes.The working principle of the AR300KL.25 rotary potentiometer is based on the Voltage-Divider Rule. This states that the current flowing through a circuit is divided in proportion to the resistances present in the circuit. And so, when the spindle of the potentiometer is rotated, the resistance between the two terminals changes. This change in resistance will affect the division of the current flowing through the circuit.The other main feature of this type of potentiometer is that it can be used to adjust the output voltage or current of a circuit. This is done by adjusting the position of the spindle to the desired resistance.In summary, the AR300KL.25 rotary potentiometer is a great device for designing and controlling circuits, as it allows for the measurement of a wide range of current and the adjustment of output voltage or current. As such, it is often used in motor control, power electronics and other applications.
