Kohlrausche's Method. Insert a variable resistance R (of bridge box) into one gap of the metre bridge, and the unknown resistance into another corresponding one at the other end. Connect the telephone to opposite ends of the bridge wire, and the wires from the S coil of an inductorium to the centre of the copper bars on one hand and the rider J on the other. Or the bridge box may be employed instead by substituting SC for the battery B, and the telephone for the galvanometer Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Birch, De Burgh.
