sary for an exact balance may without error be calculatedby proportion to the first decimal place. Metre Bridge.—For greater precision in comparing resistances theMetre-bridge may be used. The two resistances to be compared are placed at P and Q, and apoint of balance upon the stretched wire is… … Fig. 94. name of the bridge, and is stretched over the scale, so that the positionof the point of balance may be read to within a millimetre. Theconnecting conductors are, stout copper strips, the resistance of whichis for most purposes negligible. In the laboratory form shown in Fig. 95, P and Q…
