Description:

The Livingstone Rheostat Sliding Metal Brush is a precision variable resistor designed for laboratory experiments, electrical prototyping, and instructional demonstrations. Engineered with a 255-ohm resistance capacity and rated for up to 1 amp, this sliding-type rheostat enables smooth adjustment of current flow in DC and low-frequency AC circuits. Built with a metal brush wound on high-insulation porcelain, it offers thermal stability and excellent performance under repeated use. The linear motion brush mechanism provides accurate resistance modulation, making it ideal for teaching Ohm’s Law, simulating load conditions, or controlling motor speeds in controlled setups.

With robust materials and easy-to-read scale markings, the RHEOP255 model supports educational and industrial environments requiring dependable resistance control. Livingstone’s commitment to quality—backed by its Australian-owned heritage—ensures durability and consistency, even in demanding electrical environments. Suitable for physics labs, vocational training centres, or electronics workbenches, this rheostat balances function and affordability in one compact unit.
