One-Meter Single-Wire Potentiometer

This one-meter potentiometer features a single 24 SWG constantan wire stretched along a meter scale subdivided in centimeters and millimeters. The wire is clamped to heavy plated brass end plates fitted with heavy-duty 4mm socket terminals, and the assembly is mounted on a polished hardwood baseboard. The potentiometer is supplied with a jockey for making contact at precise points along the wire. Dimensions are approximately 1.13m x 80mm x 50mm. This instrument is used in physics experiments for comparing EMFs, measuring internal resistance of cells, and studying potential dividers.
