Rheostat – 8.5 Ohms 5 Amps (Single Tube Variable Resistor)

This high-performance Rheostat (8.5 Ohms, 5 Amps) is designed for accurate control of electrical current in educational and laboratory environments. Featuring a durable single tube construction, it is wound with heavily oxidised resistance wire to ensure consistent and reliable operation during experiments.

The resistance element is mounted on a heat-resistant porcelain tube, providing excellent insulation and durability under load. The unit is supported by robust metal die-cast feet, offering enhanced stability and long-term use in busy classroom settings.

Ideal for demonstrating variable resistance and current control, this rheostat is a key component for hands-on learning in electrical science.
