RUS225E

Rotary Potentiometers

Rotary potentiometers, also known as rotary resistors, are electronic components that measure voltage in a circuit. They are used to provide an adjustable voltage in a circuit, or to control the flow of electrical current. The RUS225E is a rotary potentiometer used in a variety of applications. It features a two-circuit design, with one circuit providing the adjustable voltage, and the other providing a reference voltage. The device has a maximum operating voltage of 5V and can handle up to 10 mA of current.

The RUS225E works by passing a varying current through an adjustable resistor. The resistor is connected in series with a fixed resistor, and the two resistors act as a ‘potentiometer’. This means that the adjustable resistance of the RUS225E can be used to alter the voltage in the circuit. The adjustable resistor has two terminals, one connected to the adjustable resistor and one to the reference voltage. The voltage at the adjustable resistor can be adjusted by changing the amount of current flowing through the resistor.

The RUS225E is suitable for a variety of applications, such as power supply regulation, motor control, signal conditioning, and protection circuits. It can also be used in audio and video applications, such as tone and volume control. The device is available in a range of resistance values from 10 to 1000 Ohms.

Rheostats

Rheostats are another type of electronic component used to measure voltage in a circuit. They are adjustable resistors that can be used to control the electrical current in a circuit. Rheostats are similar to potentiometers, but they have two extra terminals, the current carrying terminals. Instead of a reference voltage, the current carrying terminals are used to control the current in the circuit.

The current carrying terminals of the rheostat are connected to the adjustable resistor, which is connected to a fixed resistor. The adjustable resistor is adjustable so that the current in the circuit can be set to a required level. The current flowing through the rheostat can be adjusted by changing the resistance of the adjustable resistor.

Rheostats are available in a range of resistance values from 10 to 1,000 Ω. They are often used in applications where current needs to be controlled, such as lighting control, motor control, power supplies, and signal conditioning. The RUS225E rheostat is a common choice for these applications.

Rheostats are extremely versatile components and are used in a variety of applications, from industrial to consumer electronics, and from medical to aerospace.
