Rotary Potentiometers, Rheostats

A rotary potentiometer, also known as a rheostat, is an electrical device that can be used to measure and monitor a wide range of electrical signals. The 73JA10K rheostat is a potentiometer, which includes a piece of metal or plastic that is attached to a voltage control knob. The knob is connected to a knob shaft that is able to rotate within 180 degrees. The metal or plastic part of the device is in contact with a conductor or resistive element, that depending on the knob’s position, can adjust the transmission of power or control the transfer of current to or from the working circuit.

Application Field

The 73JA10K can be used in a variety of applications and is commonly used in automotive, electronic, or industrial contexts. One of its main uses is for the purposes of regulating electrical current, voltage, or power flow in electrical circuits. Potentiometers are also useful in applications such as amplifiers, volume/tone control, or light/motor speed control.

Working Principle

The principle behind the 73JA10K is quite simple. It consists of a rotary knob which can be rotated within a range of 180 degrees. The knob is directly linked to a shaft with a piece of metal or plastic attached. This metal or plastic piece is in contact with a conductor or resistive element, which adjusts the transmission of power or control the transfer of current to or from the working circuit, depending on the knob’s position.

The 73JA10K can be used to measure voltage, current, or resistance. When the knob is rotated, it alters the resistance as well as the position of the metal/plastic component. This alters the voltage, current, or resistance being measured. The 73JA10K has multiple terminals that can be used to monitor the output of the device, as it has 3 of them located at either side of the scale.

The 73JA10K is versatile and can be used in different contexts, as it is a robust and reliable device. It is highly accurate and can measure values within a range of 0 to 250 ohms. Its range of applications is extensive and it is a must for any electrical engineer.
