Eisco Rheostat 55 OHM

Useful for a variety of laboratory demonstrations, this 55Ω 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 55Ω * Maximum current 2.3A * Coil Wound Length (Approx.) 250mm * Eisco type PH1150E
