Rheostats Market to Reach USD 2.5 Billion by 2032, Growing at 5.16% CAGR

The Rheostats Market is experiencing steady growth, fueled by its crucial role in regulating current and voltage across industrial, commercial, and educational sectors. Estimated at USD 1.59 billion in 2023, the market is expected to grow to USD 1.67 billion in 2024 and reach USD 2.5 billion by 2032, registering a CAGR of 5.16% over the forecast period from 2024 to 2032.

A rheostat is a variable resistor used to control electrical resistance and adjust current or voltage in a circuit. Although newer electronic components like transistors and microcontrollers have replaced rheostats in many modern applications, they remain essential in high-power and educational environments where mechanical reliability and real-time resistance adjustments are required.
