7286R5KL.25

Rotary Potentiometers, Rheostats

The 7286R5KL.25 is a type of rotary potentiometers and rheostats. These two terms are often used interchangeably, and they are similar, but they actually differ in their application fields and working principles. This article will look at the 7286R5KL.25 and its application field and working principle.

Application Field

The 7286R5KL.25 is a rotary potentiometer and rheostat which is mainly used as an adjustable voltage divider. A potentiometer acts as an adjustable voltage divider, reducing the input voltage in proportion to the shaft position, whereas a rheostat reduces the current in proportion to the shaft position. The 7286R5KL.25 is often used for light dimming, speed control, fine-tuning, and other volume control applications. It is also often used as a replacement for a resistor in some electronic circuits.

Working Principle

The 7286R5KL.25 works on the principle of a variable resistor. A variable resistor is an electronic component whose resistance to current flow can be adjusted to regulate the flow of current in a circuit. The internal construction of a rotary potentiometer or rheostat is a resistive element with a contact which is movable from one end to the other. The contact is generally attached to a shaft which is connected to the knob and can be easily manipulated by the user to adjust the resistance. When the contact is rotated, the resistance between the two ends of the element changes, and this alters the flow of current in the circuit.

The 7286R5KL.25 is constructed with the resistive element and contact described above, but it also includes an additional conductive element which acts as the wiper. The wiper acts as the connection between the contact and the circuit, and it is what moves in relation to the shaft position to adjust the flow of current in the circuit. This distinct feature of the 7286R5KL.25 allows it to be used for more complex applications than standard rotary potentiometers or rheostats.

Conclusion

The 7286R5KL.25 is a type of rotary potentiometer and rheostat. Its application fields and working principle are different from standard rotary potentiometers and rheostats. It is typically used as an adjustable voltage divider or as a replacement for a resistor in some electronic circuits. It works on the principle of a variable resistor, and its distinct feature of its wiper allows it to be used for more complex applications.
