Rotary potentiometers and rheostats are both components within electrical systems used to measure and adjust voltages. The 81A1A-B28-A13L is a rotary potentiometer that is 1/2 watt, with a linear taper, and is front panel mount. It can provide a smoothly adjustable voltage or resistance level, and has a long precision life with a standard resistance range of 10k ohms.

A rotary potentiometer is an electrical component with three terminals. It is usually made from a conductive resistor, which is used to adjust the current within an electrical system. Potentiometers are ideal for small signal adjustments, and are commonly used in audio equipment, such as volume knobs, tone controls, and various other applications. The potentiometer works by adjusting the resistance between two sides of the resistor, allowing more or less current to flow. The 81A1A-B28-A13L has a total resistance of 10k ohms.

A rheostat is similar to a potentiometer, but it only has two terminals. Rheostats are used to control larger currents, and to regulate voltage in power supplies or lamp circuits. It works by adjusting the resistance across a resistor, which increases or decreases its resistance. Rheostats are commonly used in electric motors, lighting, and heating systems, or wherever a regulator is needed. The 81A1A-B28-A13L is not a rheostat, but it could be used as one if the additional terminal is eliminated.

The 81A1A-B28-A13L rotary potentiometer is a durable and reliable component that can provide accurate voltage readings. It has a long precision life, and is easy to use. It is one of the most common potentiometers used in audio equipment, as it can be easily adjusted to control the volume or tone of an audio signal. Besides audio applications, the 81A1A-B28-A13L can be used in various other devices, such as engines, motor vehicle wiring, and home automation systems.

In summary, the 81A1A-B28-A13L is a rotary potentiometer with a linear taper and a resistance range of 10k ohms. It is used in audio equipment to control the volume or tone of an audio signal, as well as in engines, motor vehicle wiring, and home automation systems. Although it is not a rheostat, it can be used in similar applications if the additional terminal is eliminated.
