Useful for a variety of laboratory demonstrations, this 37Ω rheostat provides a variable resistance in electrical circuits. Oxidized constantan wire is wound on a vitreous enamelled tube. A sliding contact carriage, mounted on the slide bar, carries a phosphor bronze contact for long life. The rheostat has three binding posts with 4mm sockets for electrical connections: one at each end of the winding and another at the end of the slide bar. * Resistance: 37Ω * Maximum Current: 3.2A * Eisco type PH1150K https://elecena.pl/product/27243855/eisco-rheostat-37-ohm-3-2a 2024-11-12 https://elecena.pl/product/27243855/eisco-rheostat-37-ohm-3-2a 2025-08-11
