Kelvin Bridge
The Kelvin bridge was designed to measure low resistances in the range of .00001 to .01 ohms. The device consists of a calibrated manganin rod with a maximum resistance of .01 ohms. One potential terminal is fixed, the other is a sliding contact. The 15 inch scale is divided into 100 equal divisions of .0001 ohm. Unknown samples 3/8" in diameter and 18" long can be measured.
