Rotary potentiometers and rheostats are two common types of resistors. Both of these devices can be used to reduce and control the flow of current through an electric circuit. They both have applications in a wide variety of industries, from large-scale applications such as the automobile industry and industrial processes to more consumer-oriented uses such as radio and home theater systems. While they have different working principles, they can both be used to accomplish the same electrical output.

RES7K5 Potentiometer

A Potentiometer is a three-terminal resistor with a sliding or rotating contact known as a wiper that sets the level of resistance in the circuit. A potentiometer works by adjusting a tap to different positions along the resistance track. As the wiper moves, it develops an electromotive force (EMF) proportional to the position of the wiper. The relationship between the position of the wiper and the EMF is often called the transfer function of the Potentiometer. The RES7K5 Potentiometer is a standard-bodied, single-turn, round knob with a voltage divider attached. It has a range of 0-7k ohms with a tolerance of 5%.

This Potentiometer is typically used in audio applications to adjust the volume of a sound system, or in mechanical systems to adjust torque or speed. It can also be used in applications such as automotive fuel and brake controls, light dimming, and low voltage control. The RES7K5 Potentiometer has a precision-crafted finish that provides superior resistance to dust, humidity, and airborne particles while also providing maximum tactile feel and operation even in extreme environments.

RES7K5 Rheostat

A rheostat works in a much different way than a potentiometer. It is a two-terminal resistor in which the resistance is changed by applying a voltage across a resistor element or by varying the current passing through it. The RES7K5 Rheostat has a range of 0-7k ohms with a tolerance of 5%. This rheostat is typically used in applications where precise control of power is required, such as lighting, audio equipment, and medical equipment. The RES7K5 Rheostat can also be used for variable power supplies and other applications such as battery charging circuits.

Unlike the RES7K5 Potentiometer, the RES7K5 Rheostat does not require a voltage divider or wiper. Instead, the resistance value is changed through a variable current passing through the resistor\'s terminals. This current is controlled by adjusting the voltage across the terminals. The advantage of the Rheostat is that it is simpler to construct and it can handle higher currents than the Potentiometer.

Conclusion

The RES7K5 Potentiometer and Rheostat both offer variable resistances with a range of 0-7k ohms and a tolerance of 5%. The Potentiometer is typically used in audio and mechanical applications, while the Rheostat is used in power control applications such as lighting and medical equipment. Both devices have their individual strengths, and which one you use will ultimately depend on the specific requirements of your application.
