Rotary Potentiometers, Rheostats

Potentiometers and rheostats are both types of variable resistors, essential components in electronic circuits for controlling voltage and current. A rotary potentiometer is designed with a knob or dial that can be turned to adjust resistance levels, thus varying the output signal. This allows for precise control over devices, such as adjusting the volume on audio equipment or the brightness of a light. Rheostats are similar but are usually used for higher current applications. They can regulate the flow of electricity, often in power settings, like dimming lights or adjusting the speed of a motor. These components are fundamental in applications that require fine-tuning of electrical parameters.

Rotary potentiometers and rheostats find applications across various industries including automotive for dashboard controls, in professional audio equipment for balance and tone adjustments, and in consumer electronics for volume control. Their characteristics such as ease of use, reliability, and precision in control make them indispensable parts of many electronic devices. Among the several manufacturers that produce high-quality rotary potentiometers and rheostats are Bourns, Inc., Vishay Intertechnology, and Honeywell International Inc.
