, and how by means of this high potential currentto force large charges into electric accumulators or condensers and bydischarging these condensers in oscillating circuits to produce what wecall electric or ether waves. These operations can be represented graphi-cally or diagrammatically, as in… … Fig. 29. The secondary winding of tlie transformer is of many turns, in orderto give a high potential. The transformer also has an iron core. Thegreat number of turns of the secondary winding, added to the effectproduced by the iron core, gives the circuit containing the secondarywinding and the…
