rrent to be meas-ured is then sent into the coils, and their mutualaction tends to place the movable coil parallel tothe fixed coil against the torsion of the spring, S.The amount of this force can be ascertained bydetermining the amount of torsion required tobring the movable coil back to its zero… … Fig. 224* Siemens Electro-Dynamometer, current to be measured. The deflecting force,and consequently the current strength, is there-fore proportional to the square root of the angleof torsion, and not directly to the angle of tor-sion. Dyne.—The unit of force. The force which in one second can…
