ecause of the slowness of its swing.Siemens employs an electrodynamometer with coilsmade of very thick wire for the absolute measurementof strong currents, such as are used in producingelectric light. It is possible also to use an electro-dynamometer as a Power-meter to measure theelectric horse… … Fig. 125.
