Rotary Potentiometers

RNS7R5 applications and working principles provide a convenient way to control the resistance in circuit parameters. It is typically used in electronic equipment to adjust the power output, light intensity, and sound volume. The rotary potentiometer is basically an adjustable variable resistor. It consists of a resistive element, an end-stop activator, and a shaft. The resistive element is usually constructed from carbon or a film-type thin metal, while the end stop activator is typically a form of metal spring.

In operation, a rotation of the shaft is required to move the end-stop activator to the resistive element. As the end-stop activator approaches the resistive element, the adjustable resistance increases. The rotary potentiometer is connected to a power source. As the shaft is rotated, the resistance changes accordingly. The resistor can be adjusted from 0 to infinity. Commonly, the power output in the application is adjusted according to the current power consumption.

The RNS7R5 also allows the connection of other components to the shaft in order to control the resistance of the circuit. In this case, multiple circuits can be connected to the shaft to produce a variety of resistance values. This makes it useful for setting up complicated systems. It is also often used to fine-tune the power output in electronic circuits.

Rheostats

Rheostats utilize the same process as rotary potentiometers to control the resistance in various circuits. However, rheostats use an electrically conductive material to adjust the resistance instead of an end-stop activator. The rheostat changes the resistance by altering the current flow between two electrodes, which can be activated by moving a knob or dial. The knob or dial are connected to an arm that presses against the electrodes.

When the arm is moved, the resistance of the circuit changes. The resistance range can usually be set from 0 to infinity, making it useful for a wide range of applications. The most common application of rheostats is to adjust the power output of electronics from 0 to a specific level. Rheostats are also used in circuit protection devices, such as current sensors.
